My settings are:
https://prnt.sc/pjw1o3

now I have 86% progress compared to already collected runes, why bot does not sacrifice?

now crash after 3 seconds in Settings

Unfortunately not

5.1.6B5 crashes 25 seconds after entering into Settings (ACC)

I confirm, many people are waiting for the update, thanks

Please update something before vacation

I have 5.1.4.0 and gem search works only once, just after the bot launch, when the gem is found the bot doesn't start searching for another. Gem searching works fine during tavern tasks, but during city guard the gem searching does not work. Also, Gem Mine upgrading level 20+ doesn't work. Gold Pit ...

ok, I noticed that the gem searching works fine during tavern tasks, but during city guard the gem searching does not work.

I didn't. I have default setting between 00:00:00 and 00:00:00.
btw at 15:39 the gem searching ends, I will check if something change until the end of the day ....

Yes, all my gold is also "available" gold, always over 500 millions, so this is not the problem.
I would like to help somehow find the bug but nothing comes to my mind.
