Could you please link a file with steps to reproduce, or post steps so I can reproduce the issue from scratch? Thanks.
I do not have the original file as I deleted it after the problem manifested itself.
You'd have to create a long animation using classic tweens and possibly the same symbols throughout. The problem arose when I'd been working on the project for a particularly long amount of time as the longer symbols have been present in the animation, the more they shift about. I am assuming that every time I moved frames about or did any kind of keyframing or tweening, it caused the symbols' rotation points to shift in miniscule increments each time. After a long time, they had shifted so much that it looked like all the animation at the start of the project was breaking apart, whereas the stuff that I had just worked on looked fine.
I suppose I could try and replicate this issue by opening another flash with a long, complicated timeline and fiddling with it until the issue reoccurred.
Are you talking about the transformation point (the point where the symbol rotates around), or the rotation values using the Transform Tool or hot text? One guess is that you're seeing a long-standing Flash-ism that is exasperated by hot text. Matrix math occurs in the background, which calculates/rounds values (always has, very old code). However, with something like the new hot text you have many more calculations being made, so the more rounding means the farther values can deviate from their original settings. I'm not sure if this is what you're seeing though. If you have steps or a file with steps as to what to do/look at, please let me know and I can investigate.

it will be difficult to replicate this problem again without making another huge project, but I may be able to by fiddling with one that already exists.
