See if either of these will work for you. 1 batch via Ni, 1 batch via dltcep. For dltcep I
a) run dltcep
B) select edit area (are.wed)
c) select file/load area/then select ar0334 with the resolve names & preview boxes checked - press OK
d) AR0334 will be the file listed in the wedfile window
e) click edit wed (opens new box)
f) click edit tiles (opens new box)
g) click save tileset.
As soon as AR0334 is displayed in the wedfile window the .mos, .wed, and the 3 .bmp files should be in your override. The .tis won't get there until the last step.
The dltcep file fixed the crash I had to enter Cromwell at the docks.
I had no issue with Arlax smithy but Cromwell was crashing my game when clicking at his door (no loading, just bing and game frozen).
Thanks very much for sharing
