Cache invalidation fails to delete TGUI bundle

[ike709]

[DEBG] opendream.res: Cache hit for tgui.bundle.js but hashes did not match (hash: 4D-9A-01-D4-88-D9-53-D4-75-42-87-D1-2A-1C-CE-6B-5E-F2-11-12-91-26-9C-8F-81-97-5A-68-2E-4B-4E-B6). Re-requesting!
[ERRO] net: 127.0.0.1:1212: exception in message handler for MsgBrowseResource:
System.IO.IOException: The process cannot access the file 'C:\Users\Ike\AppData\Roaming\Space Station 14\data\OpenDream\Cache\127.0.0.1.1212\tgui.bundle.js' because it is being used by another process.

Jumping back and forth between Paradise and TG causes the above error on both codebases and breaks TGUI.

Manually deleting the cache while the game is not running fixes TGUI.

My entirely uninformed assumption is that CEF is already using the TGUI bundle.
