Game crash while working with blueprints

[kroll]

When I'm working with the blueprint and have basic schema for reinforced plate or rotor - after unloading the blueprint the game crashes.

Long story short: Do not use short belts in Blueprints until fixed

Thanks for such quick response. I'm pretty new and could you please clarify what the short belts are? I have some conveyour belts that are really close to the mergers/splitters or other buildings to have everything fit inside - are those the problem?

[anmana]

If I have to guess that might be the reason but to be honest: I do not use Blueprints at the moment and can not define what a "short" belt is regarding this issue. You might want to do something similar with longer belts to see what is happening but in the end it is a bug which most propably get fixed soon.
Devs mentioned they are prioritizing bugs which causes the game to crash at the moment.

Thanks for the help

Summarizing things up

I did some research and found that in my case the problem was with short conveyour belts attached from Conveyour Wall props to buildings. After removing them and saving the blueprint it managed to work and clearance finishes without game crash.

For using such blueprints it will be easier to simply add those short belts manually and work with them like that untill the bug is fixed.

However, if someone who expierence the same crash and this workaround don't work for you - try to look for any short conveyour belts you have inside your blueprint (mostly near splitters/mergers, since buildings have enough space between to not create such short convyour belts).

Hope that will help anyone who gets there with such problem.

P.S. Also, if even after you trying to manually remove the short conveyour belt you have the game crash - unfortunately but you will need to delete the blueprint and create it again from scratch.
