I am running diplomacy latest version and noticed a mini dump at random times. Once it dumped I could reload at a previous time and then could predict the dump.
I believe i isolated it to the market "pricing pact" of the Trade Alliance. When anyone agrees to this pact I get a mini dump. I fixed that problem and then noticed that the pact actually makes everything cost more - it is not a price reduction. Below are both fixes.
3rd line from the bottom "pactUnlockEntityDefName" change the value in the quotes to "RESEARCHSUBJECT_PACTBONUS_MARKET"
2nd line from the bottom "perLevelValue" remove the negative sign.
