----

**UE4 Version**
4.23.1

**SkookumScript Version**
4.23.1

**Describe the bug**
When removing a variable defined in C++ and then recompiling, the Sk IDE will still show that variable until a restart.

**To Reproduce**
1. Remove a C++ UPROPERTY'd variable from a class.
2. Compile and launch the project
3. Look in Sk IDE and notice variable is still there
4. Restart Sk IDE and notice variable is now gone

**Expected behavior**
IDE gets updated without requiring a restart.
