Gond Gate doesn't allow you to choose which color of mana to produce

[behaigo]

Describe the bug
Gond Gate's second tap ability says "{t}: Add one mana of any color that a Gate you control could produce."

To Reproduce
Steps to reproduce the behavior:

1. Have Gond Gate, Sea Gate, and Cliffgate on the battlefield
2. Assign R to Sea Gate and U to Cliffgate
3. Activate Gond Gate's "{t}: Add one mana of any color that a Gate you control could produce."
4. Gond Gate produces R without a decision prompt.

Expected behavior
Gond Gate should be able to produce either U or R

Desktop (please complete the following information):

• OS: Windows 11
• Version [2.0.14-SNAPSHOT-08.08]

Additional context
I have attached the save state immediately prior to the error occurring.

Oddly, after reopening the save state, Gond Gate is working as expected. The bug seems to have been temporary, though it might still be worth looking into. If not, feel free to close this report.
