Mod Tweaking - Captains Edition

[EnterElysium]

Hey,

when trying to make some changes to CE (simple rename to zip, extract, alter, rezip, rename - right?) I changed a mere single number in one XML file but now when I boot up my altered versionb of the mod instead of the original it no longer shows the 'F' loading logo and will crash as soon as I click continue.

Any ideas why this is? I don't understand how FTL is differentiating between the two copies of CE and why one has the 'official' CE loading screen.

Where did you change the value?
And did you uninstall the other version of FTL CE first?
