Hi,

With the last version of AutoDrive mod, Factorio in 0.17.79, every time I try to rotate a modded pipe I got this error and all the functions of the Autodrive stop working.

114140.228 Script @underground-pipe-pack/lib/event.lua:37: The mod Autodrive caused a non-recoverable error.
Please report this error to the mod author.

Error while running event autodrive::script_raised_built (ID 77)
autodrive/control.lua:2343: attempt to index field 'entity' (a nil value)

Thanks for the report! Underground-pipe-pack raises the event with "created_entity", but I assumed there'd only be "entity". Quick fix: Remove lines 2386 and 2343 (the lines starting with "vdebug" at the beginning and the end of the function) from control.lua.

Should be fixed in 0.1.27/0.2.7!
