I too have a problem with IUb. What is it with the ships they are all halve submerged.I was attacking convoy {ak13} and all the ships were halve submerged doing 7 knots the strangest thing ive ever seen.but apart from that IUB is a good mod.Oh nearly forgot
Large tanker x 2 (took 3 torps)
Large gargo x2
medium cargo hit it with 2 torps and it travelled for about ten miles or so then sank ,and i missed medium tanker.
ps this game is gonna get me divorced :
AMD athlon 64 3000+
1gb ram
geforce 4 ti 4200 (i thinks its on its way out )
