Could someone explain this? (Gauntlet-fee)

[Megamieuwsel]

On one of my glads this has happened a few times now: Whenever she fails a challenge Greedy Jimmy demands a really ridiculous amount of coins for a re-try; About five times what he charges my other glads in exactly the same situation.
I mean; Having to pony up 66963 coins where my other glads (regardless of level) can get their retry for about 13676 feels a bit odd.(Same place in the run; I just tested.)
Like a bug even.
Note this ONLY happens on Theev, running the nightmare-gauntlet. Not on any of my other glads.(as far as I've seen, at least.)

Have a screenshot of it, but I don't meet the post-requirement yet.

Stable: The Hohouse
Glad: Theev
