So as I started playing the campaign and got to level 18 where all of sudden I had a full army that was killed off by a single projectile from the Toxic dead in the garrison. The projectile was stuck in a loop animation floating in the air as it dealt constant damage to my units which were all in one group. Surprised and confused I still kept playing when it came to the point that my archers arrows were doing the same thing but instead of dealing damage to the enemy units it dealt more damage to my own units. So after leaving the level to change my loadout, nothing a happened for a little bit but until I realized the same Toxic dead from before was still in the garrison and the projectile bug still kept wiping out my units. So not letting it stop me there because I did managed to win and this bug lasted until level 21 where it stopped.
I originally thought the devs added a impossible level that players are not meant to go past as the rest of the game is still wip.
And I did find it funny because the fact this was all happening in normal mode. XD
Sadly I didn't take any screenshots because it was impossible to capture a projectile bug without it looking like a normal screenshot and I didn't have this discord at the time.
