Today I organized a concert and after it took the proceeds from the cupboard.
I had two packs of coins: ~20 CROWNS and 50 Canes Venatici.
I divided the coins by 10 per pile.
After make piles to 50 they began to disappear (i mean piles). After repeating this action my CROWNS desappear and i have only 30 coins of Canes Venatici now...
I can't reproduce this in any trivial way, but I'm also not sure I can follow your step-by-step guide.
Have one pile of 20 and 50 named coins of two different types.
Use Right Click -> Make piles and split them into stacks of ten.
Then what? What do you mean by "After make piles to 50 they began to disappear"? That when you went to split the 50 stack you lost coins?
Can you reproduce this bug yourself? Has anyone else seen it? I would love to fix it if it checks out.
"The psychological trials of dwellers in the last times will be equal to the physical trials of the martyrs. In order to face these trials we must be living in a different world."
1. Make stacks of 10 -> Now I have 7 stacks of 10.
2. Make stacks of 50 -> One stack desappeared (6/7).
Return to 2 -> Another stack desappeared (5/7).
Return to 2 again -> I have only 4 stacks of 10 (4/7).
And again -> Only 3 stacks of 10 (3/7).
I think this only happens when you have two different types of coins in inventory.
"The psychological trials of dwellers in the last times will be equal to the physical trials of the martyrs. In order to face these trials we must be living in a different world."
I have been able to reproduce the bug. Simply, it is connected to the traveler sack inventory bug. If you shift clicked your tsack to put it into your inventory, it disapears sometimes. Moreover, this creates another bug with the coins, described in the OP. When you have a hidden tsack and you attempt to make a pile, 1 stack of coins will disapear to nowhere. When you will get the hidden bag out, everything works normally.
