Im having the same issue with my resource base boat. I only get gold and I have plenty of space and all resource bases are mine.
I've tried to report the issue within the game but the game crashes every time I try to send the message.
Game crashes after typing my message and sending it. A new message appears asking me to select a reason. When I click any option, the game instantly crashes.
When I reload the game and go back to the message, I can see that a reason was never selected. If I try again, the game crashes.
The result is my messages never go through
