Hi there, I am experiencing the same or a similar issue as well.
I am on Ubuntu Budgie 18.04 and the panel is having issues with the applet display order as well. Unlike the above issue though, I don’t think I’ve experienced any crashes though.
I have added the budgie-extras-daily ppa and ran the software updater then rebooted. I also confirmed that showtime, dropby, and quick note were all installed. Other issues I found that were similar said something about the weathershow applet causing issues so I removed that from my panel as well and nothing has changed. I’ve tried reboots and removing applets as well as added the three applets mentioned above to the panel just to see if that would help.
It seems like something at the end of the panel causes issues if I were to guess stemming from the above user’s(@siebenHeaven) mention of a segmentation fault and the ever present off by one error in programming. I too have the bottom two applets not being allowed to move downwards, which is strange as the second to last I would expect to be able to move below.
Lastly, I noticed that if I run nohup budgie-panel --replace & multiple times that the order of the apps especially near the end of the panel changes each time its rendered.
I don’t know if @siebenHeaven ever got their issue fixed as they didn’t update us, but it would be nice to know.
If there is more information that I can provide, please let me know and I would be happy to! This has been more or less one of my only issues with Ubuntu Budgie so I would love to get it fixed! 
Thanks a lot!

Hi and welcome. Yours sounds different.
If you reset the panel and repeatedly restart the panel at what point does your issue return?
budgie-panel --reset --replace &
