I have exactly the same problem and them the ts3 begins to annoy with The voice saying "error" is also spamming the TS chat with this:
Action currently not possible due to spam protection. Please wait a few seconds and try again.
i guess that it may be caused by the "ts3 ACRE plugin" would you be able to update it guys? please. :pet5:
the plugin is not supported by ts3 :/
TS3 Version: 3.0.13.1
