The new 0.2 beta build is up
http://www.assaultware.com/RangeMeister.latest.zip
Unfortunately, auto updates cannot be rolled out right now because of the NC 2.1 beta blocking the versioning system. Alternatively you can reinstall as the install has been updated.
This version aims to solve 3 issues:
-filtering not working correctly
-errors on non english PCs
-PT3 marked hands not appearing
if you still have a problem with filtering, I apologize in advance but I was never actually able to replicate the issue
I did make some changes to the suspected problem. Anyways, if it still doesn't work, please advise me as to what you're trying to filter on and also if possible send me a log
