Please report this error to the mod author.

Error while running event Landfill_plus::on_tick (ID 0)
Unknown tile name: unbreakable-landfill
stack traceback:
[C]: in function 'set_tiles'
Landfill_plus/control.lua:143: in function <Landfill_plus/control.lua:104>

Thanks for the bug report.
The problem should be fixed in version 1.0.7 it was caused by disabling breakable landfill. But I would still recommend having it enabled because disabling it during a save will leave grass spots under the player and machines on landfill and the deconstruction tool shows landfill tiles that aren't mineable.
Have a great day!

Okay, thanks for the fast fix! Have a great day too :)

I couldn't reproduce the issue. What did you do to get the error message? And were you on the latest version (1.0.7)?

I got the error when playing Warptorio expansion and biters were on the warp platform while warping.
Yes, I was using the latest version.

I just updated the mod (1.0.8) tell me if you are still getting error messages.

Ok I finally found out what the problem was. It is now fixed in version 1.0.9.
Have a good day!
