The item description issue is explained here:
https://www.subsim.com/radioroom/sho...t+descriptions
So I need to also transfer
UPCLocalization.tsr file in Data\UPCData\UPCLocalization\
from TMO or FORTSU and see if it will not mess-up my stock equipments. I hope not.
[EDIT]
This will not work, while you get infos for the torpedos, you won't get descriptions for upgrade items or for what's in your boat currently; the description windows for 'On base' and 'On boat' remain blank.
