This is for both nations and towny, I believe a large number of tickets are caused by random things going missing from chests in claimed towns, usually taken by people with trust.
Problem is many leaders of towns don't necessarily know if it was taken by someone that is supposed to have those things, or if it was taken by someone that is not supposed to have those things. So of course this leads to a bunch of time wasted that is taken from both the reporting town member and staff team.
I suggest a block logging tool/command that could only be used in your own town if you have a certain rank (or maybe not a certain rank as sometimes low ranking members have stuff taken aswell) so you can check who and what was taken and have a non-ticket alternative to getting your items back. Would also speed up tickets in the case of someone purposely stealing things.
