Can't find enough tickets to progress in Chemdah

Hi, I've tried to google around to no avail, but I'm nearing the end of the Chemdah areas and am just short of getting to level 26, which unlocks the next path. I can't find any tickets and feel like I'm at a dead end. Sorry if this has been asked before.

There's a gap here that just gets undiscovered everytime I leave it.

Here's what it looks like, just in case.
