invalid arithmetic operator

Created by: nikooo777

Shell: 5.0.17(1)-release

Operating system: 
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.3 LTS
Release:        20.04
Codename:       focal

Liquidprompt version: c5d630d5291dab83eb36cf760a541e093eb8a410

Steps to Reproduce

1. Clone latest liquidprompt
2. source ~/liquidprompt/liquidprompt
3. type any command

Expected Behavior

no error. also on the next prompt line I should see the error code of the previous command if it's not 0

Current Behavior

~$ echo test
test
-bash: Please ask your administrator.: syntax error: invalid arithmetic operator (error token is ".")

with no error code on the new line if there is one

Possible Solution

I have no clue why, but doing the following:

git reset --hard HEAD~1
exit
reconnect...

fixes the issue. additionally, at this point I can advance 3 commits into master and the error is completely gone. Not sure why that is.
