Can confirm. It still kills the player kobold, thus deleting all of your money and also resetting progress on the objective. So until the dev fixes this (which I assume shouldn't be too much longer), you are going to have to delete all containers, swap bodies with a sacrificial kobold (thus keeping your kobold), then you save. The best way to save your money is to stockpile the money ITEM and only pick them up when you need it.
Bright side, loading the save also unlocks all the buildings, so you can focus entirely on kobold farming.
EDIT: It seems you do have to buy the construction contract before loading the save though, or else you lose out on the grinder
