Bots tried to place a substation, causing a crash.

Crash log:

I'm seeing the same error in 1.0.6, traceback line numbers are a bit different though:

Hey, thanks for reporting this! Strangely that traceback leads to a part of the code that does check for entity.valid, so I'll need to look further into this. I can't recreate this by just having a bot place a substation, would one of you be able to provide me with a blueprint or screenshot that causes the crash? Thanks, SleepyStew

I didn't try to place a blueprint, rather my bots tried to place a substation which had been destroyed by a pentapod, this also happens when it gets destroyed by a biter.
