Sorry i'm not using the bug template, but I don't think it applies here.
Got this a moment ago:
Expression exception during export.
Function class era::IExpression *__cdecl
Build: release 120.2 (64-bit) checked
Componen: Construct 2 IDE
(Last Win32 error: 0)
(it would be great if in future versions, these errors could be easily selected for copy and paste, cos writing them from screen to forums is a pain :)
I used a loader layout in one of my projects, I went to project properties and changet it to not use the loader layout and deleted the layout that was used as a loader layout, previously changing the "first layout" to some other.
In the loader layout I could have had (sorry if its not proper english - not my alma mater :) a constant global value, so it may be related to it.
