Dear Sir/Madam,

There's a point where you need to defend a poison tree from 3 waves of enemies but it is bugged and i'm unable to complete the objective/mission,

This bug most likely happens when you do a finisher/execution on one of the enemies during either the start of the chapter or defending the poison tree objective.
I do not know which enemy types make this happen exactly, but playing through the mission without executions made me go further with the campaign.

Here's a video of the bug being already active. It's around wave 3 that this happens.

And here's a video of me playing through the campaign without any executions.

I hope this information helps.

Kind regards,
Boris Vasic
