<Negative values in the "Companion Overview" at towns (https://www.aworldoficeandfire.co.uk/forum/v8-0/negative-values-in-the-companion-overview-at-towns/)> by me
I found out the cause and the solution! There is not enough level checking in a script. It checks only level 1 thru 30 (That was enough for Brytenwalda), and does not support AWoIaF's NPCs with higher levels.
My hand-disassembly of current code:
jq_xp_to_next_lvl, script.txt,

I checked NPC with max level in troops.txt, experimentally added else_try blocks for level 31 thru 50 to "jq_xp_to_next_lvl" in scripts.txt (and increased the number of operations), and got correct result.

In addition, the script is called from not only town's market-menu but also [Report]-[Companions Overview].
- How to reproduce it/when/why it happens:
Hire companions who have higher level than 30, Visit a town, select "Trade with locals", select "Companions overview", and see the column "to next lvl".
- Game version (and steam or downloaded):
AWoIaF v9.1, v8.2. Warband v1.174 downloaded
