When I put the game version switch into T2a, maps of two kinds of weapons error and status panel showed no damage, this is how to return a responsibility?
it's because of packets.
client will show you sth with server's settings.
if server returns the packet about expansion with T2A settings, client will show T2A settings only.
so, you should change settings of packets on Core script.
File Direction : ServUO\Server\ExpansionInfo.cs
Find ExpansionT2A = T2A,( it might be placed in Line.68 )
Change ExpansionT2A = T2A | LBR
