Possible temp fix for the mess that is tactics.

Having reported and mentioned the tactics issue many times, without any form of response from EA or Admin, i may have stumbled on something that works. It does for me, hope it helps you.

Tactics were not saving, I only had 2 slots to change in- game, go to Team Management in game and I couldn't back out, starting matched with a formation I hadn't chosen, players in wrong position, etc.

I realised I had a set of tactics from an objective, these seem to still be working, so I can use my 5 set ups. It's possible i had these before the update messed anything up. Due to lack of response from anyone, i thought i'd give it a go, and seems stable for now.

Good luck.
