If you feel, the first two could be your issue, either just click on upvote on these posts or add some info to either of the threads, depending on what fits better.
From what you are describing, I'd say these could be the visual issue since you say they are fluctuating.
- Reach Rank 3 / Adept -- will fluctuate between 0 and completed
- Learn 5 Spells -- will fluctuate between 0 and completed
For the duel, create a new thread here: The Sims 4 Bug Reports | EA Forums and just describe what happens for that particular one. Make sure to include thread tags for your platform and mod usage.
For the evolve one: Did you evolve excellent plants or normal ones ? Could be any number of things with that.
Do you have any others ? Usually it's best to create one thread per aspiration but if it's fluctuating it's probably more of the visual thing happening.
