I am playing te first misssion of the gale where you get "dark angels". Despite the capture of a temple I cannot get them to spawn. I have no trouble getting black knight but I can't get dark agels.I can finish the level regardless because I don't want to start over, but I would like to know if nowdays Gog has fixed this 10 years old bug.

No, that bug is still there with GOG.
You can either download the fixed levels: https://keeperklan.com/downloads.php?do=file&id=141
Or get GIM, which has the fixed levels included: https://keeperklan.com/downloads.php?do=file&id=109

Yeah, I wish they'd do something about this. Played patch 1.7 one time back in the day with my orginal CD version and had the no Black Knights and Dark Angels thing then. Never again played with 1.7 after that and just default 1.1 or whatever is on my CD.

Bought the GOG version and noticed it had 1.7 too. Played the whole campaign without Knights and Angels again. I'm pretty sure Goblins don't spawn in like final 5 missions either.

Can there be a previous patch download or something here on GOG? I know there's a new creature in 1.7, but I never play skirmish, so don't even notice that.

GOG never offered 1.5, so you can't even roll back to it.
Use the fixed levels that Loobinex linked to.

is this the fix you're looking for?

Yea, i am at the last level right now, and very sad about that Dark Angels and Black Knights not only not spawning but I can't even sacrifice combo the BK. Everything else is coming from the temple, except that. What sucks, because I can't get the level 10 Dark Angel either - I don't have any BK to sacrifice.

GoG should really fix this very annoying bug.

They should, but the patched levels linked above your post will fix it.

Hey, not sure what I'm missing but this patch doesn't seem to be making any fixes for me.
I've restarted the level, returned to the campaign select, etc, but building a combat pit yields nothing on the final level, while I get a Salamander the instant I build a training room.
