Thanks Algor, I will find a way to work around, np.

So I have one more issue to report. It is a minor one and difficult to reproduce, so maybe don't waste any time with it.

When generating random maps and the WoG option to ban spells on shrines is used, it can happen that on all level 1 and (maybe) level 2 shrines the spell is set to 0 = Summon Boat.
My guess: It has to do that the old !!FU$spell$ function still relais on returning y-99.

WoG 53 map options.erm

I did some test...

yeah long story short, there somewhere is a problem, but it only occurs randomly when y-99 is set to zero for some reason.
Ways to prevent it:
-use no big mods (these make the error occur it seems, for example ACM)
-Dont use these wog options
-Dont ban any level 1 spells

Or restating the map can also help. If the first Shrine you visit is okay then there will be no problem at all, otherwise you can restart the map.
