Well, I tried again when editing with ERM.
For test starting I just changed the last description:

Water Walk Water Walk 4 x 12 8 8 8 0 60 60 80 100 10 10 10 10 10 10 0 0 10 15 15 20 25 "{Dissipation} <-- here


Added SPTRAITS.txt in H3bitmap.txt.
Added the new file in the wog. file
Added the others as required (H3sprite.txt empty)
Then compiled the files and ran update. This time it says the file is broken and can't update.

I also added INSTMULT.txt but nothing.

Then I added the original SPTRAITS to the package just to see: says file is broken. So it must be a path error.

@Darkloke,
Can you help me getting the last graphic working? It is only CABEHE which has a palette error. Here are the two files needed.
