Just reload the extension and it will start working again, it's a bug.

But, I understand your concern and have made the requested changes.

The upgrade was hastily put and the current limit is 3 not just the one. And I have already increased the limit to 50 and submitted it to the store.

A new upgrade has already been submitted but it'll take the dev team a day or two to give it the green light and roll out the new version.

Seems like people don't even want to make a one-time contribution, I will be discontinuing the support and will be not replying to threads after the next update.
