I was playing WCIII reforged and this bug happened. The first part was during the prologue campaign when I have to build a camp and rescue Hellscream. I was just building the camp and the mission ended with defeat screen. Another one was in Arthas (Human) campaign, I was just defending the town (Heartglen, may be misspelled) and the undead didnt even penetrate my defenses and the mission ended abruptly with a defeat screen. What the heck is that and why?
Dang must be rough when i did the heartglen mission i defeated the undead main base instead of defending mainly.
I don’t remember having any issues with those missions, but somehow it doesn’t surprise me.
