For IC reasons, I did not want to send telegrams to my entire region utilizing the Communications power. I had it revoked to have it send with stamps instead so I could maintain my other RO powers, but I am still unable to send the telegram. Instead, I received the following error:
"Sorry, only nations with Communications authority may wire free Mass TGs to their region.
New Officers are also required to hold office for at least 26 hours."
It does not seem there is a way for regional officers to send mass TGs unless they have Communications power.
