Able Ability System Info and Support Thread

@ HELP! I made abilities that branch and they work absolutely perfect on sever. wont work on dedicated servers client. I mean they DO work, but they always branch.
Heres the setup:
Melee start - Check if can trigger.
Ok run
Theres a branch condition on 90% ability - IF Input -hold (negate) than branch to ability fast attack. (in general if you hold and charge heavy attach it will go to next branch… if you release while branching it will perform quick attack instead)
Another branch 90-100% of ability - takes you to heavy attack idle - a channeled ability.

My problem: On dedicated server the client instantly goes into fast attack. 1-2 frames and whoop! fast attack.
What am I missing to make it work on dedicated server?
