Chimera Stuck after Monster phase

chimera fight was running good, then on about 25% he went in SHADOW PHASE AND at same time he started the Add Wave's , never saw that before, My Golems (Hexagolem, can lie dead on ground and See golems killing) killed the adds, then i went back to the room and walked in the shadows to unreveal him. Then it was like he was there for a second but bugged out and is now out of the Map (on the High point on the south where is standing and watching always) at 25%


I see this Bug is since mid of last year AT LEAST , so nearly a Year without a fix

Please Fix it GGG, Many people in the past lost currency by that and if you dont change it they will loose also in future!
