Great map!
Did crash though, had to use the beta branch, else it would crash on load once you reach "the" room near the end.

I'm assuming that it fixed your crashing problem, then? I haven't tested but it's the only thing that makes sense. If so, you are very welcome!

In your Steam library, right-click Half-Life: Alyx, click Properties, click Game Versions and Betas, click on the Previous Release option from 2022, and then wait for the update to finish. If everything works fine then on a fresh save, the new update is probably the reason.

Damn that’s insane, I didn’t even know that. Thanks for informing me, I’m not really sure how to roll it back but I’ll figure it out

@matinprsd & @matador
Nobody had crashing issues in this mod until Valve updated HLA on Sept 14th, 2026. If you are having problems with any of the custom maps in the workshop then please roll back to the May 6th, 2022 update and I imagine it will all work from a fresh save. Also be aware that custom creators can't even open the Workshop Tools in the new build so they can't even go in to try to fix it. Hopefully Valve remedies this problem soon.

This mod is amazing, but no offense, it is way too ♥♥♥♥♥♥♥ crashy. It’s consistent too, it will crash back-to-back when I load up save files just to try to get back into the game. I literally couldn’t even finish the gameplay.
