I’m actually in Canada; I’ve had it happen once during locals in Toronto when things used to be run inside a game shop (this was back in 2016), then 3 more times during club sessions at my university (once during a session in late 2017, another at a session in early 2018, and another at a session around March). For what it’s worth, the sticks in question used:
- A Hori Fighting Commander board (Xinput version) + MadCatz TE 360 board
- A Hori Fighting Commander board (Xinput version) + PDP MKX Xbone/360 board
- A Hori Fighting Stick Mini 4 board + PDP MKX Xbone/360 board
All the lock ups/disconnects happened while playing on PS4.
If it really is the dual mod (whether by how good my modding job was or if 2 boards are drawing too much power at once), I’d have to consider undoing them completely and just sticking with PS4, which sucks since I spent money on those Xbox boards and drilled holes for switches already.
