I have notice that it now takes me many tries to summon my conjurations. Some have suggested that this is related to using spell absorption. I did recently pickup the Atronach perk under Alteration, but I am not 100% sure if this is when my problem started. Does anyone know any tips or ways around this?

It is an other bug, unluckily. Check http://www.uesp.net/wiki/Skyrim:Spell_Absorption for more info.
