BPM changes that are less than 4 beats apart don't convert properly in Psych charts

[swordcube]

I am trying to convert a Codename chart to a Psych chart, however I noticed that BPM changes that are less than 4 beats apart seems to create incorrect behavior

The beginning of the song is supposed to go from 175 -> 160 -> 150 -> 140 -> 130 -> 175
However it seems that it jumps from 175 to 130 (with a bit of delay) then back to 175 (with a bit of delay again)

These BPM changes occur a beat apart from each other
Psych charts have a sectionBeats field, but it seems like it isn't really utilized at all in moonchart

Video 2 (actual behavior)

The 2 videos are recorded in 2 different FNF engines, however i don't think it is an issue with the engine shown in Video 2 since if it was, then psych charts with standard 4+ beat separated BPM changes probably wouldn't work properly either! (they do work just fine)

It's working better than it was, but it seems that it generates some sections with 0.5 or 1.5 section beats
This messes with camera movement events and such since those start executing noticably late/early
