AGAIN you have screwed up the patches for this game. Now we have:

Patch (1.0.7 to 1.0.8b)
Patch (1.0.8c to 1.0.9c)
Patch (1.0.9c to 1.0.9c+)
Patch (1.0.10b to 1.0.11b)

So, missing is 1.08b to 1.08c and 1.09c+ to 1.010b. Do you have chimps managing your batch scripts? Holy shit, how can this happen so frequently?

Edit: Oh yeah, and why does this patch (1.0.11b) have a "b" suffix when it's just 1.0.11 from the developer?

Linux patches stopped at 1.0.5
I think there is a way to help GOG.com - open a vacancy page and find one I'm interested in. Actually there are two at least. Hm...
