getspldscr: bad splnr (solved by lch)

[pyg]

So I've been playing with very large mods and I've been hitting a bug that I don't understand. I get a crash with 'getspldscr: bad splnr' when I click for spell description in research on spells added by mods. I'm pretty sure it isn't a bug in the mod because I can get the crash with spells from two different mods.

My first guess is that there is a hard limit on #newspell calls although I can't find it in the documentation I have. The crashing mod calls it 157 times. Can someone confirm this or tell me a different direction to pursue.

I have also gotten a crash with a 'bad splnr' during hosting (different method than 'getspldscr' though, can't remember exactly). Re-hosting the turn would sometimes finish with no errors.

If it would help I could post the mod and a .trn but it would be very large ~3M zipped.
