Note: I'm writing this up for a patron of AoF7... English is their second language and are not comfortable in it.

In the patrons words (they use computer translation, I was told):

It feels like you only have an extremely small area where you can press

Some examples they shared:

Worst Case They Had

The phenomena was gone when getting down to X / Z: ~50,000 / ~50,000.

I'll look into it
