i honestly dont think they will make a tweak for patch x. Remember we still have patch y and z that hasnt been made. If any thing i personally think the devs will make the tweak for s3
Look if the two .exe files (BeSpoke.exe and LFS.exe) are in the same folder. (*this is important*)
1. Start Bespoke.exe
2. Start LFS.exe
3. Alt+Tab /or if you are in windowed mode/ click BeSpoke -> /optional/ File -> Open, open your desired rim file.
4. LFS -> Export to LFS
it happened to me when the BeSpoke.exe file was not in the same directory with LFS.exe. Make sure you have the correct release of BeSpoke for your current version of LFS. (BeSpoke for Patch X, and LFS with Patch X)...
