I'm having a bizzarely specific issue. When I search for obj_player it returns a different item (specfically scr_itemuse(which is a script)). It doesn't seem to do this with any other combination of Objects/Scripts. I've tried restarting the software and haven't noticed any changes. I'm still able to open the object manually, only the search function is having this issue.

Currently running Beta from December 28 on a windows 10 Laptop.

Update 0: reinstalled (completely deleted then re-downloaded) the Dec 28 beta, still got the same issue. When I reverted to the Stable March 24 release it seems to be working fine again. 

The issue turned out to be use of "function" (which is now a reserved keyword, on track to be an actual keyword in 2.3) as a variable name, confusing GMEdit's indexer (which assumes code to be somewhat valid) as result.
