What happen to EoR?

@Ptirodaktill If I were you, I would test

  • putting EoR on 0 - 9
  • making RMB hold spam EoR button (or maybe even RMB itself if we leave EoR on RMB)

You can use GDAutocaster for that
I’ve tested and EoR is fluent then and you should never need to re-press+hold RMB again if your issue is the same as quoted one.
If EoR is on 1 then config (GDAutocaster.ini) would be

[general]
suspend_key=Tab

[periodic casts]
cast1=RButton:1

The button is spammed with 1 press / 100 ms frequency by default.
