Thank you very much, MaverickMongoose,
What a great find, and thank you for reporting it. I did not even think about this being different in 2025.3 vs 2026. So I explore this with my file from above:
Can you spot where one render stops and the other starts? Both just run to frame 32, the yellow without caching, the red one is cached first.
The 2025 is on the left, the 20026 is on the right.
I can't spot a significant difference, while each simulate will have some random results in it.

I thought I could add to the report, but I can't reproduce it.
Fingers crossed they find what makes it on your end different; it might show up in other setups more pronounced, and then we will be happy to have had your input, so again, thank you.
Have a great weekend as well.!
