[Outdated][Bug 1.30] Crash

Hi

I seems to have an issue where I have a rather large factory and production line, and the game often crashes with the following error message:

The crash can be generally be brought on by restructuring the resource conveyors, especially when paused. Once restructuring is complete (and if paused, unpaused), the frame rate drops significantly. It is often at this point that the game will crash.

I have the savegame if that helps.

Thanks in advance.
