AI made a trade to the bank and then did nothing, the dots were just next to its name saying it was making a turn and that's it. Clearly some protection mechanism needed to wake the computer up in these instances or just apply a hard 5 minute timeout on turns regardless of the other optional timer. It can be a bit painful waiting for someone because they've forgotten to click turn over for example.
Same here. Very disappointing that this bug is still here after 9 months. Seems to be worse in the latest patch.
