EDIT: Looks like the problem was from the base game, 0.18.12 patch seems to have removed the error! Apologies if you're already aware of this, but I've just got an error with the newest Factorio version (0.18.11) and wanted to pass it on! Happens when deconstructing a chute with personal robots ... ...

Also got the crash from opening the lab menu, just started a fresh world after the update.
