# Mouse side / thumb buttons stop working after TAC update — Logitech G Hub path mismatch

You bound your mouse's side / thumb buttons to in-game actions via Logitech G Hub (or Razer Synapse / Corsair iCUE) — for example "thumb1 = grenade, thumb2 = melee" — and it worked perfectly. Then after a few days, the side buttons stop responding. The mouse still works for normal click + scroll, but the customized thumb bindings don't trigger anything in CODM. Reported framing:

"I found that out when suddenly my mouse side thumb button stopped to work... in g hub I had added gameloop exe to customize profile and found out when I opened gameloop next day, it was running exe from different folder with different version number."

Root cause: TAC silently auto-updates on startup, and the new version installs to a slightly different folder path than the previous one. Logitech G Hub (and similar customization software) binds profiles to specific executable paths — when TAC's path changes, the G Hub profile no longer matches and falls back to a generic profile that ignores the thumb buttons.
