Problem

---

Due my modding project XMS2 i discovered that arma somehow bugs some code out so that it is not possible to execute it without runtime issues

(check the code below)

#include "\X39_MS2_Scripting\default.hpp"
/*

there is no issue inside of this peice of code

but arma thinks different:

Error in expression <else>Error position: <else>
Error Undefined variable in expression: else
Error in expression <else>
Error position: <else>
Error Undefined variable in expression: else

(sometimes arma also prints that the operation _unit = _x would be invalid ...)

this only happens if that piece of code is callen in a function (in the ESC debug menu it works fine)

Any ideas?

BTW animation ""AinjPpneMstpSnonWrflDb"" in Arma 3 used for drag wounded or dead bodies attached via attachto command not working well - body is in ragdoll state and isn't conecting to carry unit,  only after detach body is moving to drop position instatntly.
