Error while running event Warmonger::on_tick (ID 0)
Warmonger/control.lua:74: attempt to index field '?' (a nil value)
stack traceback:
Warmonger/control.lua:74: in function <Warmonger/control.lua:56>

Can't reproduce. And code logics is ok too for standard use cases.

Did you use special QoL mods to rotate installed building? Like picker dollies. Probably not. What's the catch to rotate building in trouble...

nothing rotated, only placed with a blueprint. and shortly after it crashes, not always, only one time.

Placed blueprint with ghosts over creep and bots built it, correct?
Can it be some scripted buildings in that blueprint? For example buildings from mods like ItemCollector or its derivatives: SchallPickupTower, etc. ?

I'll add a check for this and similar situations in several places. At least to be on safe side. Such buildings in un-supported situations won't be damaged by corruption :-( .

yes, correct, i have a scripted building, my smart linked chest.
but if it were the bluprint content, then the error would always occur with me.
