G'day mate
Easiest way to do it as a short-term fix is to go into Deepin.
Make sure it is up to date.
Code:
sudo pacman -Syy
#followed by
sudo pacman -Syu
Fire up Timeshift.
If you haven't got Timeshift on it yet
... should work, let us know if it does not.
In Timeshift, Delete any snapshot you already have, of the Deepin spin.
Check with your Settings (is it still jlap4) that you have both the user line and root set to all.
Run a new full on-demand screenshot of Deepin.
When completed, use the comments field to label appropriately.
Jump out of Deepin and into one of the other MJRO, that has Timeshift.
Use that one's GParted (they are all current, so should have an up-to-date e2fsprogs component) to BLOW AWAY your Deepin'.
Then use its Timeshift to restore your Deepin. Make sure that the / root partition, and the ESP it is going to restore to are those which they should be. Even Timeshoft can get confused, with multibooters
.
When the Timeshift is restored, reboot and you should have your Deepin back on top and your Theme restored.
When that is done we can talk about how to keep it there (mostly).

Note that for Manjaro you no longer need to use yaourt to install. You can do it with sudo pacman -S timeshift
