build error monkey island 2 german amiga version

[gabberhead]

extracting game resources works, but when u build it right after the extraction, i get this error:

DOBJ not yet supported Rebuilding game resources: GAME ┌─────────────────────────────── Traceback (most recent call last) ────────────────────────────────┐ │ in build:63 │ │ │ │ in rebuild_resources:178 │ │ │ │ in update_loff:164 │ └──────────────────────────────────────────────────────────────────────────────────────────────────┘ AttributeError: 'NoneType' object has no attribute 'to_bytes' [26060] Failed to execute script 'runner' due to unhandled exception!

extracting txt and import it, this is working.
