lnet high cpu usage

[Xanlin]

tldr; I think I may have caused a problem with lnet by training in a spell and then untraining it (and having no spells after untraining). How do I fix it?

Everything with lich has been running great, until today. This morning lich crashed, and after I exited and restarted I started seeing almost 50% cpu usage from rubyw.exe.

After killing off all of the scripts it settled back down to .15 ~ 2 percent. I started running scripts again I narrowed down the issue to lnet. When I kill it, everything works fine, when I run it everything crawls and cpu spikes and holds above 45%.

I tried downloading a fresh copy of lnet from the repo, but still have the same issue. Tried rebooting, checking that antivirus wasn't messing with ruby both without any luck.

After checking out the debug log and scripts, I think I may have caused this issue by training in a spell and then untraining it.

This is the debug log I get whenever starting up and connecting lich:

Followup:

I checked my #{DATA_DIR}/#{XMLData.game}/spell-ranks.dat and the file was there but empty. I closed lich, copied spell-ranks.dat from another computer that had it for this character, and everything seems to be working okay now.

Usually when you mess around with spells you can type in SKILLS BASE and ruby usually fixes things. Not sure if that would have helped. Maybe next time.
