1 month ago 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.
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:
"Invalid index table header magic. This map could be compressed, try the Compressor in the Tools menu before reporting."
Full output:

To Reproduce Steps to reproduce the behavior:
