I use the Anti Offline Raid plugin for my server and would like to make it compatible with in-game teams (by default on Rust). I made this change to the code but I can't get it to work, I get errors on the conversion from ulong to string ... (I'm not good and used to using c #). Could anyone tell me how to fix?

The problem is mainly in the 801 line. Like: cannot convert ulong expression to string.

you dont need lines 799-801 delete them and change "mid" on lines 802 and 804 to "memberid"
