I've just try play this game on fresh clean (1s after install and delete "all" files from all directories) firefox and 1 battle crash. I've lost 2 sculls (24h) becose this, game is totaly unstable after latest upadtes. And memory leaks are ridicles (after ff update). Invalid mutators used on database nice testing team. Put more buy this buy thet pop ups, every one will love "game" with pop up to close.
If you experiencing bug with invisible bosses you need to delete cookies from mighty party and kongregate (300-400mb MP and 50 m KG) and then restart browser.
I found solution it appears bosses are there but they are invisible and you need to click entire screen to find them and then they suddenly appears (wierd).
Hi event (horn of plenty) is bug out boss screen show only errors (to switch bosses).
There is no way of any interaction with screen.
Clearing browser cache does nothing changing browser from firefox to opera result in gray screen after pressing play button.
O after tring to fix 1 bug (and contacting to "server menagers") from times this game show up, new featearers shows up like memory leaks 500MB per battle and very unfear ballance like ai enemy can spawn 2x more units then me hehe. What a mony grab same as 2 other games from this developer. My advice dont waste time on titles like this. Have a good day.
