I am playing a game with the Ruins Mod and I am encountering this error when I attempt to claim buildings:
The error is as follows:

The mod Disco Science (1.1.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event DiscoScience::Custom event (ID 236)
DiscoScience/core/labRenderers.lua:87: table index is nil
stack traceback:
DiscoScience/core/labRenderers.lua:87: in function 'changeLabForce'

<DiscoScience/control.lua:19>
stack traceback:
[C]: in function 'raise_event'
AbandonedRuins/control.lua:111: in function

After this, the game returns to the title screen.

Thanks very much for the report! It looks like I missed something when adding compatibility. I will try and address it soon.

Thanks. I will be happy to provide a save file if necessary

1.1.3 should address this issue. Thanks again for the report!
