Freezing when accessing Stash due to MASSIVE network traffic spikes?

I’ve noticed the game often “pauses” or “freezes” for a short period (less than a second) when moving things in/out/around my stash - the more I do this, the more noticeable it gets…

Just looking at Windows ResMon I’m seeing CPU/GPU dropping-off whilst Network Traffic spikes (specifically from Lastepoch.exe) - then everything returns to normal

The game is going from a small amount of in/out traffic to a LARGE amount of traffic - it doesn’t SEEM to be a “ping” issue it seems to be actual data being transferred which is taking so long it’s “pausing” the game

My guess is there’s anti-duping or other checks being done but it’s quite intrusive and I’m not sure why it gets worse the more you do it (are you resending information unnecessarily??)

I’m going to dig into this more as it’s fairly easy to reproduce - I just thought I’d raise this initially as I can’t see any threads about this issue specifically (and I probably missed it??)

p.s. it strikes me it’s probably getting worse as I have more things in my stash but this issue happens even if you don’t change stash pages - are you literally resyncing the ENTIRE stash with every pickup/drop action !?
