Tomb of Miktrull Chest bug - Don't have fire lamps to burn vines around switch

Happened to me too. The targeting with force push has a lot to be desired and if the lamps don't break or are extinguished by water, they won't respawn when they fall into free air.

I did what DoodleDrew40 suggested. I carried a lamp from the first area past the gravity well and down the hallway. I aimed for the peak of the arch at the end and after a few tries the lamp passed through the water and burned the vines.
