Issues with bundles on Flea market

I noticed two errors when trying to sell bundles of items on the Flea market

A: Once the bundle is sold, it only reports one item being sold with the rest of the offer still up. The offer vanishes if the server gets restarted or the player tries to cancel it (as seen in the server log)

B: Items sold as bundle are reported with the same tax as if they sold singular, yet thats not the case and the actual tax deducted from the players money is magnitudes higher than stated by the game. The first sell in my log for example were 13 9mm RIP rounds for 800 R each. Ingame the fee is reported to be 4082, actually deducted are 9504.

This error doesn not appear when selling items singular, here the tax is displayed correctly
