Oops. I accidentally posted in the wrong forum. How to migrate this thread to the "Development" forum?

Vanilla forum is fine for reporting bugs - the development forum is mainly for talking code issues.

Thanks for the report.

Update: it turns out that the list of spells the monster can cast also is not shown until a reload.

It is getting curiouser and curiouser. Sometimes I get partial information about the resistances before saving and reloading. For example I just met a lesser Maia. I'm fairly confident I never saw this type of enemy before. I activated the rod and now I know that lesser Maias are resistant to poison, confusion and sleep, but other information about resistances is still hidden.
Edit: Apparently the partial information I saw was displayed before I used the rod. Is it because I have a high enough CL (29)?

{unconfirmed} The information about the spells lesser Maias have didn't show up even after I reloaded the game.
Edit: {confirmed} even after I reloaded the game the information wasn't there until I let the Maia cast both its spells on me.
