Achievement Won't Unlock

[JudahCarvanna]

Product: Command & Conquer Remastered
Platform:Steam-PC
Summarize your bug Life... Finds A Way Achievement won't unlock despite having completed the fun park missions multiple times.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? Complete all 5 fun park missions. If the achievement for completing them doesn't unlock, you have the same issue as me.
What happens when the bug occurs? The missions complete, the achievement doesn't unlock.
What do you expect to see? An unlocked achievement upon completion of all 5 missions.

‌

Other achievements have unlocked since, so it doesn't appear to be an update issue.

There is a potential workaround (not a fix as it requires playing the mission(s) again that the achievement is missing, after deleting the file which tracks ingame progress). I posted it in this thread:
