hey folks, is here someone who made a multiple controller supported game in the past? we have an issue when we use multiple controllers. everything works well in editor mode, but when we build it the inputs are messed up and don´t work anymore... can someone help?

In this video the guy talks about this issue and how he tackled it:

Dude, we had the EXACT same issue with our jam entry, 'Duet'. Unity is infamous for having a terrible legacy input system. With like 6 hours until the jam was over, we broke down and got Rewired. I honestly can't recommend that plugin enough.
