Integer overflow when pillaging?

[Autolykos]

Hi!
I've got the following situation:
1) I've captured a settlement (22k inhabitants) with a horde, part of the horde disbanded, everything fine.
2) I've razed all buildings and bulit my own temple, still everything fine (except heavy revolts, but that was expected).
3) I've horded out of the settlement. A horde of acceptable size appeared, there was no rebel garrison in the settlement (I recon this is normal?).
4) I pillaged the settlement. The Income from pillaging on the button was at about -2 billion, and so was my treasury after pillaging.
I can reliably reproduce this bug (It's in a mod with WIP, so I can't help you with savegames).
Has anyone seen something like this before? What are possible fixes?
Also, my game whines because I set the horde_max_units_reduction to 0. Could this be a problem?

On the money issue. Most probably an integer overflow indeed.
On the horde one: Yeah, try at least 1, I'd say

Ive seen this happen in vanilla BI as well. Once I was the Franks, I formed a horde at the start, and sacked Vicus Franki which is the starting settlement for the Franks. The income was a very big negative number.

I've seen this as the Goths also. For whatever reason, if you sack a settlement you just horded from and has no units, you get a huge deficit.
