Hivers, time has come for the community to understand how to synchronize data to get each player his own customized UI 
I'm doing a unit selection panel (check picture provided) and I'd like it to work separetely for each player. It's running fine in solo but I will get automatic desyncs in MP when someone use the buttons.
I've isolated the display parts into GetLocalPlayer() condition block and the only thing I'm doing is to set variables in these blocks to check their value after so remaining actions are executed for everyone.
I've ran a test setting a local integer to get the id of the clicked button inside a GetLocalPlayer() block and use his value after it, this leaded to a crash for every other player.
Then I've stumbled upon this thread trying to understand how I could synchronize my data. I've ran the same test with my local integer but this time with a gamecache and synchronize call methods, it also leaded to a crash.
According to @Taysen, one must call the BlzGetFrameByName function at least once for every players before using it in GetLocalPlayer() blocks, so I did an "anti-desync" function that just use this method upon every frame I got in my unit panel to avoid desyncs.
Now I must confess I feel a bit blocked, here the code involved in the process. ID_XXX are just global integers declared in the same script file.
I hope I can solve it asap because my alpha release is nearly finished
Thanks !
Callback function when a frame is clicked inside the unit panel (pressing the "roll" button will create a desync issue)
