Actually not sure what the problem is. Been away for a few days and did a bunch of updates and now with questfu/guildfu/friendsfu/channelwatchfu I can hover over them a few times and the tooltips appear but after 3-5 times they just don't appear anymore. No error at all.
I don't use fubar just fortress and fubar2broker. Tried rolling back the versions of guildfu/fortress/fubar2broker with no improvement.
