I read all bug reports that are posted in the bug thread. I try to read all posts.
I solved why I didn't get my ritual spell working: I used #eff instead of #effect...
The command for summoning a creature might be wrong. It's 3 - an uneven number! If #effect list of effects is a bitmap, it can only have various powers of 2. 2^1, 2^2, 2^3 etc.
