The only way to fix the saves and send them back was to remove the function which redraws all gold/mithril costs and updates hints. So player buys something, the future costs are not updated unless he opens again the dialog.

I use in that function two color codes (red for not enough resources, green for ok) then the rest of code is trivial, and already used in many other DL which never had any problem/

This is the function crashing the saves (on players configs, never on mine)


Now, if I had at least one constant crash, I could start debugging by cut in the code and see. But as it never crashes on my system, no clue what to do with. If you get the crash when loading that save and click on ability to buy, could you please, when some free time, to see which part of the code is guilty? My bet is on lines 26 to 29.
