You using the standard or 4k version? I fixed the one for the 4k UI (rustle2.4k) and it looks the exact same to me. I could probably download and fix the standard version the same way.
Edit:
Okay I tried fixing the standard too. I loaded it up once and it looked way smaller, but I didn't do any death testing. Give it a go
EQUI_Inventory.xml for Standard
EQUI_Inventory.xml for 4k
