Sounds a bit like a GOG specific problem not related to a missing update in general but I might be wrong here of course. I only know that GOG should have the most recent version of Wuppo. Since I own the game on GOG and on Steam I will compare the versions later.
SirPrimalform: Apparently Wuppo is missing an update, but I think we need more details from the OP.
Actual Steam version is at 1.1.104 and GOG is at 1.1.104 as well - so it's not a missing base game update in this case.
Checked GOGdb as well and the DLC is up to date with version 1.1.104 as well. Seems to be a GOG specific issue.
