Didn’t mean to be impolite, just thought that since my problem looks pretty much the same, it would add up. But ok, I can post it as a separate one.
I’m experiencing the same problem. After issues with saving no widget content at all and updates that fixed it, now PB refuses to save cyrillic characters. Or rather it saves them the first time but when I reopen the widget for editing, those fields are empty.
