Describe the bug
Attempting to load a stock MCC Halo 2 map in the latest public build 2024.02.14.15.24.44-dev results in the following error:

Additional context
Attempted with multiple Halo 2 maps that are all stock. This only impacts Halo 2 maps, all other games in the collection have the map files open as expected.

Halo 2 maps in MCC are compressed. You can decompress them by selecting Tools>Map Compressor. The exception mentions compression but actually for H2 MCC I could make it more clear since the state of compression is a flag in the header.
