Renux Herkanor "trained" Make Poison skill past 21

[Tnair]

She took my money and training points, while saying "I can't train you any higher!" and my skill kept rising, up to 35 or so when I ran out of training points. Skill window showed Make Poison at the same level.

Then after relogging the Skills Window showed Make Poison was back at 21, but I don't think my training points or fees reappeared.

Not looking for recompense, just reporting a bug. Unknown if it's linked to either Renux *or* Make Poison specifically since I haven't trained any other crafting skills on p99.
