Hello!
Love your mod! I hope that I can send you a crash report here. I was playing pyanodon, so that could interfere with your mod. Just wanted to share, if there is something can be fixed.

See the following text for the error message:

The mod Resource Map Markers (0.3.5) caused a non-recoverable error.
Please report this error to the mod author.
