Return to Skybird Trill - Impenetrable Rock spawned instead of lava trap

[Trickee-per]

On the free play levels > classic levels > Return to Skybird Trill

Im at this hallway where like six boulder traps rolled out and there is a line of guard posts. If any creature sets foot in there, a block of impenetrable rock will spawn where on a youtube playthrough it's a lava trap.

I couldn't find any posts about this anywhere besides a comment under a youtube with a vague suggestion that I can't get to work. I can get a mistress corner glitched into the rooms beyond but I'd like to be able to claim the tiles and rooms with an imp.

Any workaround or fix for this known or suggested?

Or perhaps confirmation that if I download and install the latest version of keeper fx (I'm running 0.5.0.3081 right now) and play through the map again up to this point that would even be fixed there?

Thanks

I believe I indeed fixed that up between version 0.5 and version 1.0.

Downloaded, played through up to the hallway, and the lava traps spawned normally. Thanks.
