You need to wait a while between each ++, otherwise it won't work...

I first applied the patch from zero1zero from here:

#21

After that, I was able to get the plugin to work. However, it doesn't seem to work if you issue "++" commands too quickly together.

For example:

jira++
Glados
jira has 1 points
Victor
jira++
jira++
jira++
Glados 12:43
jira has 2 points
Victor
jira++
jira++
jira++
Glados 12:43
jira has 2 points

So you need to issue one command, wait some while, before you're able to issue it again.

Has anybody else seen this issue?

I have this same issue as well. I am seeing:

This is an anti-spam feature, not a bug - a user can't ++ the same thing multiple times in a row.
