SRL Archive - Help

why was it moved to /core/ from /misc/?

Because we found out that it was used too commonly to be in /misc/.
Especially in association with S.M.A.R.T.

ok so it needs to be changed in any scripts then?
why am i getting this error?

Failed when compiling
Line 18: [Error] (20335:1): Duplicate identifier 'TWorld' in script C:\Program Files\SCAR 3.21\includes\SRL\SRL\Core\WorldSwitcher.scar

I get this error too :/

Don't include the file. It's automatically included when you include SRL.scar now.
