Sjizzle, that's already a very helpful link. I've started downloading and installing some of those, thanks.
I must say though- the "Generic Patcher" seems to me the most important one so far- it seems to include all of the other fixes- if you manage to actually get it installed and setup properly
Took me a good hour to sort through all the different fixes included in it! Just goes to show what a mess Ubisoft left SH5 in....
So far I've got darkwraith's new UI's, IRAI, mightyfine crew mod, crew commands, torpedo speed fix, and the generic patcher.
