Can't load/switch to new scenes that are built based on the same scene file

[cathiecode]

Describe the bug?

When you build two scene bee files, you can load one of them in a player as normal. However, when you try to switch to another, it almost always fails.

Steps to Reproduce

1. Make two scene bee file based on same scene (let me call them "Build A" and "Build B")
2. Start the player and load Build A from library
3. (Build A loads normally)
4. Try to load Build B
5. Loading fails and blank Initialization scene appears

The expected behavior

Successfully loads Build B

Build Info

Version: 0.0.1

Log Files

Player.log

The AssetBundle 'Memory' can't be loaded because another AssetBundle with the same files is already loaded.

Additional Context

It seems there are some variation of failure:

• End up with Initialization scene (purple blank scene)
• Seems successfully loaded, but materials become magenta after few seconds
• Seems successfully loaded, but objects are duplicated

Test was conducted with two remotely hosted bee files:
Build A: https://zipline.space.superneko.net/u/Test Scene Build A.BEE
Build B: https://zipline.space.superneko.net/u/Test Scene Build B.BEE
Password: test-scene
Test Scene Build A and B.zip

Currently this is unsolvable thanks to the way unity stores data for apvs needs further research
