Unable to open GM1 file

[PureTryOut]

First of all, thank you very much for this project! Stronghold Crusader was a big part of my youth and even though I never really played Stronghold 1 itself, being able to play a FOSS version of it on my favorite OS (Linux) natively is absolutely awesome!

After linking my Stronghold 1 installation to the directory the application seems to expect (../data), the game loads up fine. However, the console logs various parser errors.

[ GAME ] -> Starting version 0.1.4 (Linux)

Is this to be expected in the current stage of development and should I just have patience, or is something going wrong here?
