Can't load save game on new PC

[pepwhaa]

Hello,

This is my first post in this forum although I have been following it every now and then. My issue is that my savegame is not loading in my new pc. I have been playing this savegame for roughly 300 hours on my old laptop.

My laptops configuration is Core i7 6500u with 8GB ram and Radeon R9 graphics.

The city is built from a custom map from the steam workshop. The last savegame had 107,000 population and 1407 mods/assets.

Now to the issue: After doing countless tweaks and detailing in my city with my old laptop, the simulation and fps were getting painfully slow and laggy. Therefore I decided to build a gaming pc which would fulfill my long time wish to build one and would also benefit the gaming experience of cities skylines.

My PC specs are: AMD Ryzen 5 2600, 16GB 3000MHz DDR4 Ram and GTX 1080ti graphics.

So, excited to try my save game on my new pc I loaded the save from steam and waited for the assets and mods to sync up but to my surprise the game got stuck on the rotating loading icon at roughly 80%

I then tried copying all my mods and assets aswell as the Colossal Order folder from drive C from my old laptop to my new pc but the results were same.

Afterwards I tried running the loading screen mod to see what the issue was, and with that I saw after loading the game 80% the mod reported that
"Object reference not set to an instance of an object"

I tried loading up older saves and new maps, they all are working, its just my save game that is not loading up.

Please help me diagnose this issue, I have had almost 300 hrs of gameplay in this save and I dont want to lose it!

Please let me know what logs and files you need and I will attach them here.

Thanks!

The "Object" error just means that it's looking for an asset and can't find it.
Try verifying game files, and always use loading screen mod to load your games. (Although I know you did use it & it still didn't work) Is there anything special about that specific save? Mod? It should still be able to load after not finding a single asset.

I suggest having backup saves. It helps. It REALLY helps. Once in while, when you load your game file and everything seems to work fine, do a quick save with a separate name (just add "backup" to the file name). Don't use this file to play from, just use it to update a backup copy of the game when it works for you. I use this method a lot since I used to have issues in the beginning. It has saved me countless wasted hours when my games crap out.

My suggestion may not have any bearing on what is happening to you, but it's something to keep in mind. The last thing you want to do is load a game you spent weeks on, only to see it corrupted.

In order to load and play a viable savegame, everything that was present at the time of the save needs to be present when loading. So... you kind of went about it backwards ;)
First, on the pc, subscribe to all of the mods and assets that you used for that save.
You cannot just transfer your mod/asset folder from the old laptop to the new pc. The custom content has to come from the Workshop.
Once your Workshop is linked to the new pc and your custom content has downloaded, then enable everything that was used in the save and only then load the save.

Is that just a case of going into Content Manager and finding the save as there's a couple of buttons on the right that I thought grabbed everything from the workshop you don't currently have ?
It will take a while to download it, but should then have everything.



Could it also be that the DLC needs to be 'ticked' in that DLC box.

Thanks for the quick replies everyone. The savegame is sort of like a replica of the city I am currently living in. That's why it's a bit special to me I guess. I have other backup saves of the city but unfortunately all of them have the same issue. I guess I will try and go through the missing asset list one by one to try and figure out the issue and also will try and do a reinstall. I will also try and upload the save in the workshop. Whoever is interested can give it a try and see if the problem persists.

Does save still work on your old laptop?

Also, for new pc, don't just copy stuff over, use Steam to sync everything as that will make sure all settings and stuff are in right place. Copying files using explorer won't update various system config files, etc.

One common thing that can go wrong is if road assets are removed from workshop - that will break a save (hence me asking if city works on the old laptop).

Well? Where is it?
No need to reinstall. Just rt click the game in your Steam Library listing and select Properties/Local Files and run the Verify Integrity of Game Files app. That will ensure your game files are correct.

Then, start the game and in Content Manager/Saves, select the save and set it to Share. This will upload the save to your Workshop where you may add additional details such as description, list of required DLC's, mods and assets and name the save. Make sure you set the visibility of the save to public and then copy the link to it and post the link here.

Sorry for the delay. Here is the save game. Whoever is interested please give it a try and see if the game loads. Thanks!

BTW, in the content manager/save games, in the option to enable all the custom mods/assets used in this save, it shows 2 assets/mods missing. 766190099 and 1569957736.

After googling I saw those numbers are for the "Move It!" mod and "Align Rotation for Move It" mod.

And then searching in steam I saw that I am already subscribed to those mods, but still I unsubscribed and subscribed again but still its not working.

Neither of those workshop id's you mention exist any more.

Latest version of Move It already includes all the alignment stuff, so you don't need separate alignment mod.
