It makes me kinda wish for a friendly flood event. Not like a bunch of Flood forms appearing as allies, but just a couple or few of them.

I have absolutely 0 clue how this is happening... I'll try to work it out soon haha

The only time in the entire script I make flood allies is when the Didact spawns in for his boss fight, and that ends when the Didact dies. There are 0 other places in the script where I make them allied with anyone, so this is going to be caused by something very weird haha

same issue here. friend and i had flood allies, and flood jump pack brutes!

Can confirm that as of alpha 12 the bug still isn't fixed. It seems to specifically happen to infection forms spawned by a carrier form near the end of a wave. If the carrier form explodes earlier in the wave the infection forms will be hostile, but as the wave is winding down the spawned infection forms are suddenly friendly.

The infection forms themselves will pop on their own over time but if they find a body to infect then the combat form will also be friendly and last until death.
