Editor Bugs

1. If the editor seems to be running but you can't hit the stop button its most likely a animation blueprint or Sequencer running, Click close the editor, and when it ask you to save

don't save, and it should stop running

1. item of type Object reference doesn't match the property of type hotreload in :

Solution: Close editor, recompile, with F5, Hot Reload is buggy

The current value (/Game/Items/Weapons/Pistal/BP_Ino_Pistal.BP_Ino_Pistal_C) of the ' Item ' pin is invalid: /Game/Items/Weapons/Pistal/BP_Ino_Pistal.BP_Ino_Pistal_C isn't a valid subclass of BP_In0_Item_C (specified on pin Item)
Solution: Reslecting the class BP_In0 Pistol in The Class drop down from the class reference node parameter
after recompile and reload, I changed the Parent class from inherting from a Blueprint to c+

2. If you have can't save file error and some werid location, its most likely you have two editors open on the same process
and one of them likely an orphan process
