multisource problem

so, i'm making a map and I have a room that functions like this: you bhop to the end, press a button and then bhop back to the beginning, but you only have 5 tries to do it before the thing resets to the original state

func_button->multimanager

multimanager->
-light turns on above the button
-a func_train acting as a door moves since afaik you can't trigger a func_door without having it reset after x time
-2 multisources activate, activating 2 triggers, a teleport and a trigger_multiple(stacked on top of each other so that the trigger_multiple is on top, the multisource teleport between and the original teleport on bottom)
-trigger_multiple targets game_counter with limit value of 4
-trigger_changetarget that targets the func_button and makes it's target into null to prevent triggering this multimanager again before I want it to
-game_counter_set activates, setting the new value of game_counter to 0

game_counter->reset multimanager
-turns off the light
-triggers func_train to move back to the original position
-changes func_button target back to the other multimanager
-deactivates the multisources

trigger_multiple at the exit of this room->reset multimanager

tried so far:
- tested both multisources independently, not working
- checked all keyvalues a million times, they're all ok
- tried trigger_relays to activate and deactivate the multisources, both toggle and on and off relays

very annoying since I have 3 other multisource in the map acting as masters for triggers, all triggered by multimanagers and they work perfectly

sorry if it looks confusing but this is the best i can explain this setup
