Please add null handling.
Hello. I am currently testing out your mod, and when i pressed the visibility toggle for the signs, i started getting null reference error spam.
This is because you don't have null handling, witch is needed for RimThreaded compatibility.

Here is our wiki page on with info about thread safe coding:

Please consider adding null handling, its very simple to do, thank you.

Update:
this one might be on our end. its fixed in the next update.

null handling and thread safe collections are still needed when appropriate though.

Update again, seems its just on this mods end, not even related to multithreading

Apologies for taking a long time to get to this. I haven't spent much time with anything RimWorld-related in months.

This bug should be fixed with the update I just pushed. It would trigger when there were no signs placed yet on the map and the toggle was used.
