I found a solution that fixes the missing heads on the Gotland, Tofhelm and Rounded Topfhelm, feel free to try it
Just replace your item_kinds1.txt in the crpg folder with this one (remember back up original first just in case)
http://www.mediafire.com/?s0fs5qfj2nf3avhor you can do it manually
open the itemkinds1.txt
find and replace the words
madeInbucket with madelnbucket
gotlandbucket1 with gotlandbucket
(make sure you do this for every time the word comes up and make a backup first just in case)
for the green great helm (which appears to actually be red) to work try the following
using openbrf
open dejawolfs resource file
go to the Mat tab and select crusaderbuckets_col2
change the diffuseA from greathelms2_Col2 to greathelms2_col2
hope this helps til the hotfix comes out
