How would I disable the hints and tricks box on the loading screen? I've looked through the shipped campaign scripts and couldn't find anything about it. Deleting the tips scope with localiztion tool just gives me [NULL].

Don't think its possible.

Im not sure, but I think it may have something to do with the loadscreen files, maybe a corresponding .lvl or something?

It's probably included in the shell or maybe more likely in the common scripts. A search through each script set showed the word "tips" only appear in ifs_opt_general.lua, and I could check to see if that were it because the strings referenced in that were for the tips since I don't know where that reference is located (couldn't find it in localize). A search for common.tips produced nothing.
