Vaal Foundry (Molten vault) Waystone Map with invisible barrier after killing the boss

While playing through the Vaal Foundry (Molten Vault) waystone map, I encountered an invisible barrier that blocked my path after defeating the boss. The issue occurred when I logged out after killing the boss and re-entered the instance. Upon returning to the upper part of the boss arena, I attempted to backtrack through the upper part of the bridge where I initially entered the boss arena, but I was blocked by an invisible barrier.

Steps to Reproduce:

1. Enter the Vaal Foundry (Molten Vault) map and progress to the boss.
2. Defeat the boss.
3. Log out or disconnect from the game.
4. Log back in and return to the map instance.
5. Attempt to cross the upper bridge to backtrack through the map.
6. An invisible barrier will block the path on the bridge.
