:arrow_forward: ISSUE EXPERIENCED

Strange little bug here. When researching Iron Horse on one trade line, the upgrade is prevented from being researched on the other trade line. Once the research is completed, the upgrade affects the OTHER trade line and Iron Horse cannot be researched again. In addition, the intended trade line is not upgraded, and Iron Horse can no longer be researched.

  • Less than 25% of the time / matches I play (RARELY)

:arrow_forward: REPRODUCTION STEPS

Here’s the steps to reproduce the issue:

  1. Play a game on the Yellow River Map
  2. Get to Age 4
  3. Upgrade both lines to stagecoach level
  4. On one line, research Iron Horse
  5. Observe the research is greyed out on the other line
  6. When research is completed, observe the other line is upgraded while the intended line is not
  7. Observe the intended line can no longer be researched

:arrow_forward: EXPECTED RESULT

The upgrade should affect the intended trade line
