I'm currently playing ATM 6 and used the Infinity Range Booster, and it causes all grids to become unresponsive.

I open a grid (wireless or wired) and within a second or 2 I can't interact with any items in the system. I can put items in but it acts as though it's the first of that item I'd put in (for example, I have 2.4k Lapis, if I put a stack of Lapis in, it will show the 2.4k Lapis and a separate 64 Lapis). When I remove the Infinity Range Booster the issue stops entirely.

The system has ample power, so it's not losing power part way through.

The same thing happens with the Dimension Card.

EDIT:
It seems to happen more consistently if you do a search before trying to take something out. 99% of the time I search anything, it immediately becomes unresponsive.

Okay, after playing for a while and changing my infrastructure, it seems I've found the culprit. It's a weird interaction between Endertanks' Ender Tank, Refined Storage and RSInfinityBooster. If I have an External Storage cable on 2 or more Ender Tanks directly, the issue appears. If it's 1 or 0, no issue, and if I remove the Infinity Range Booster or Dimension Card with 2 or more Ender Tanks connected, no issue. I found out after changing my Lava and Water storage to use external tanks instead of the Ender Tank itself.

Not sure who's issue this would be, but the issue only appears with the Infinity Range Booster or Dimension Card installed so I'll keep the issue open here.
