Unless you updated the demo twice within the past 20-ish hours, you didn't fix the Fox jailer issue, as I still got an error that crashed the game when a Fox Jailer made contact with me while another one was grabbing me. The issue does not occur with Latex Dogs or other enemies, only Fox Jailers.
Apparently grappling enemies do not make any effort to avoid the normal stairs when forcing you towards the pink stairs, and walking through the normal stairs still causes the normal effect. However, you will stay grappled.
