Entities update - entities summoning

With a lot of test , the summoning system is not working most of the time. The system do not let me summoning the monster I want, the spells don't work when I want to summon a creature, the summoning system is bad in my opinion, it does not work most of the time and, when in combat I start to argue with Franz about the summoning he failed to do and me wanting him to add a creature in combat, he is not with me, he argue with me, keep telling me that he can't find or summon the creature I want, or that I must use another spell slot for HIS mistake.
