Hi
found a small bug:
- create a blueprint with a math expression in it
- change the math expression
- compile
- press ctrl-z for undo
- try to compile again (it wont)
Compiling works again after you edited your math expression.
I guess after undo/redo the math expression needs to be rebuild… which is triggered when editing.
I get this bug in 4.6.1 and also with version 4.7.0 prev 8
Happy hunting!
