Hello, I got this after updating and attempting to load into my Space Ex playthrough:

The mod Landfill plus (1.0.5) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Landfill_plus::on_tick (ID 0)
LuaTile API call when LuaTile was invalid.
stack traceback:
[C]: in function 'index'
__Landfill_plus/control.lua:129: in function <Landfill_plus/control.lua:102>

Thanks for your bug report.
The problem should be fixed in version 1.0.6. I accidentally uploaded a older version of the mod last time.
Have a good day!
