ToME: the Tales of Maj'Eyal

Whenever I'm telekinetic grasping something (gem, weapon or mindstar) with beyond the flesh activated, and equip the Cuirass, the beyond the flesh sustain starts to automatically activate and deactivate every turn. As far as i could test (training area in fortress) I didn't notice any negative effects. I mean, no damage difference, no interactions with the talents as well. But it's kinda annoying since the message log gets flooded with every step and the game gets slower.

edit 1: another weird interaction. If i remove the cuirass active from the shortcuts, as soon as i spend a turn, it automatically appears on the first available shortcut slot (for example, if key 1 has nothing attributed to it, nor is cuirass in any shortcut, when i spend a turn it automatically gets set to key 1)
