Hi!
When you enter a factory building (factorissimo2) with the latest autotrash(4.1.x) loaded, I get this message-window:

The mod Factorissimo2 caused a non-recoverable error.
Please report this error to the mod author.

And if you downgrade autotrash back to 4.0.6 things work again.

Thanks for the report, should be fixed in the latest update.

I couldn't reproduce it, from the error it looks like you stood close to a factory, the roboport closest to you got deconstructed/destroyed (and somehow Autotrash didn't notice it) and then you moved. Not sure why Factorissimo is even mentioned in the crash.

For reference: https://mods.factorio.com/mod/Factorissimo2/discussion/5d067ad08140c9000c25df5e

I cannot confirm a deconstructed/destroyed roboport.
But I can not exclude that similar happens with the personal roboport when entering the building?

No matter! Problem seems to solved!
Thank you very much for update!
