Tied Notes not holding on tempo changes

Create a score. Input a chord of at least 3 notes. Hold it out for three measures. In the middle measure input a tempo change. The notes won't hold and will halt playback. The issue also occurs for fermatas, which also drop the sound as I think the program recognizes them as tempo changes now as well.
Other factors:
- I'm inputting a score made in musescore 3 with existing ties. Though I've experienced the issue a few times in just musescore 4 as well.
- I'm using MuseSounds for playback
-Sometimes when the note is divided on the tempo change (ie, changing the beat the change is on to a quarter, then holding it again, it can work, but not always. It's very inconsistent with that)
