So I made a pretty big comment under the mod but yes, it is for sure the phantoms that drop enemies to cause the error on co-op. The phantoms that just fly around and shoot don't even seem to cause it. And this makes about 4 missions possible to beat not including Lone Wolf.

Here is what I put under the mod so it can be here in this discussion: (PART 1) So, it seems people are having CO-OP problems and I can help out a little bit, kinda. This mod is bugged but some missions are possible to beat. First of all, before playing CO-OP with someone make sure both of you are matching frame rates. Either 60 frames or 120 frames. Do NOT do unlimited frame rate as this will cause syncing problems and cause a error a lot of the time. It will even happen in the base game with no mods. Same thing with using mods in the campaign if you wanted to run aimbot etc. You would BOTH need to use it because again, syncing problems. Now, the issue is that with this Mythic overhaul mod, it seems that the 'phantoms' are breaking it. When playing CO-OP, we thought it was the Noble team allies, to normal allies such as marines and ODST AI, but nope. The most consistent thing that was breaking CO-OP was the phantoms. Especially the ones on the mission Nightfall as those phantoms are consistent and seem to always drop the same enemies.

(Part 2) Either phantoms that drop enemies are RNG causing it or something.. But I can for sure say it is missions with phantoms that break CO-OP. Mainly the ones that drop enemies and not the ones that just fly around shooting. Long Night of Solace has phantoms that just fly around and shoot during the Sabre part but don't crash and some other phantoms don't seem to crash. So if the mod creator wants to look into this, please do. The mod is great but this is such a major issue on some missions. We were only able to beat 4 missions fully NOT including Lone Wolf. And 2 of the 4 you need good RNG on a phantom drop for it to not crash which is ONI Sword Base and Tip Of The Spear. The other two was Long Night of Solace and New Alexandria which worked fine for the most part because no phantoms dropped goons. Hopefully this can be looked into because CO-OP does seem playable if it weren't for this issue.

I would say Winter Contingency can be beaten as well but you need to get passed the part when Kat is working on the door but the RNG on that is really bad and it crashes a lot on co-op. But once you can get passed that, it's a joke to finish.

Bump, I am waiting for a fix if we ever get one lul

Hopefully some kind of fix is implemented, this would be really fun to do co-op on.

Every time I see this mod get updated, I get my sister to hop on and see if this issue was fixed. We really have a lot of fun with it before it decides to randomly kick us. Hope for a fix soon!

I would simply love to play this mod in coop with a friend. I saw the update, then checked the changes without seeing a fix for the coop issue. Why are not more people talking about it?

Yeah I know but the creator does not seem interested in fixing it. maybe its due to the nature of the mod since the modder thought about it for single player only maybe. The respawn of enemies from the phantoms seems random sometimes and maybe it spawns different enemy type for each player causing the crash due to a de-sync. Otherwise why is the game crashing only during phantom enemy deployment?

Having multi-player would be great, all the misc armor abilities and weapons would be perfect for multi-player. It's a little bloated for singleplayer.

this is made for the campaign lol

multiplayer campaign

Hasn't crashed during Co-op with phantoms; but the crashes do seem to occur when the host dies.
Great mod... once it works in Co-op

crashes are still happening in Co-op, real shame. Had one on the first mission when going across the first river bed and another crash upon arriving back at the base during the Swordbase mission.
