All right. So For my mod I want to use the last section of attack on the control room but there's an issue: It won't open in sapien.

I renamed my original tag folder to _tags and created a new tags folder, where I extracted all the files from the b40 folder.

I looked through in guerilla to see if there were still missing files but none were found to be missing.

I might just have to recompile the map..... Which I don't really want to do but will if I have to.

Any tips/ideas?

wait u renamed tag? everything is linked to tag/levels/*folder and level and stuff* in guerilla so try renaming it or create a new scenraio using the last part of the bsp

Making an alternate tags folder to extract stuff to is my mistake. Reset your tags folder so it's normal then extract all the folders in the entire map recursivly with HEK+. Make sure it's set to extract to the regular tags folder. All the tags it extracts will be added to the right places in the tags folder. But some sp maps still won't open. For me, only silent cartographer works. Most others wont and some require special tags or something.
