Strange Reaper behavior regarding TS change

On the Phase Shift forum, it was mentioned that in some circumstances, the MIDI EOF writes doesn’t look the same in Reaper:

Looking at the MIDI in Reaper, it’s like it starts bunching up a couple beats’ worth of notes into one beat, throwing things out of proper place and merging notes. This happens at the time signature change on measure 139. Looking at the contents of the MIDI file myself, I’m not seeing what’s wrong, the notes that are supposed to be a half beat apart are written about 240 deltas apart from each other (in #/4 time, 480 deltas should be one quarter note and also one beat) and notes that are supposed to be a quarter beat apart are written about 120 deltas apart:

Here’s the MIDI file written by EOF:

Thanks in advance.
That’s good, I was worried it was a bug with EOF. Do you know which versions of Reaper are affected? I have a really old version (3.71) installed on my computer, as I only used it for testing purposes instead of authoring. I tried looking at the MIDI in Anvil Studio as well, but it also displayed strangely in that editor (but then again that editor has other problems like drawing measure markers as if there are always four beats per measure).
Not sure it was ever fixed. The issue is that once your TS are wrong (you start a 4/4 signature at the 3 of a 5/4 measure in example), all subsequent TS changes are messed up, no matter if you fix the incorrect one.
So should the user change the time signature to 5/4 at measure 138 to resolve this?Every TS change after the chewed measure needs to be changed, yes.
Thank you, I made that change in EOF and then it looked fine in Reaper. I’ll suggest that to the user. I may even add a warning in EOF if this authoring problem is found.
