diag.exe wipes mission when trying to preview in MP in Eden
New, NormalPublic


When trying to preview a mission in 3den in multiplayer while on the a3diag_x64.exe all mission objects are removed. When saving the mission in this state everything is lost. Loading the mission again returns it to the previous state.


Operating System
Windows 10 x64
Eden Editor
Steps To Reproduce
  1. Start arma3diag_x64.exe
  2. Open a mission (or create one, it might get lost) in Eden Editor
  3. Press Play >> Play in Multiplayer (MP)
  4. Confirm hosting a server
  5. The mission does not start. Instead all mission objects are removed from the scene, Eden displays "Scenario saved"

To revert the mission afterwards:

  1. Load the same mission again

Would be quite logical to replace MP preview button/menu action to hint dialog that will say that diag.exe does not have MP.
