### ▶ GAME INFORMATION

👇 _These details are CRITICAL; DO NOT skip them or your issue may not be reviewed._

- **GAME BUILD #:** ######
- **GAME PLATFORM:** Steam / Microsoft Store
- **OPERATING SYSTEM:** Windows 10 / Windows 8 / Windows 7 / Mac / Linux

### ▶ ISSUE EXPERIENCED

The Stagecoach button can be shown on the Trading Post even after it’s been researched by another player (AI for sure, but not sure about human players though).

### ▶ FREQUENCY OF ISSUE

👇 _How often does the issue occur? CHOSE ONE; DELETE THE REST!_

- **50%** of the time / matches I play (FREQUENTLY)

### ▶ REPRODUCTION STEPS

👇 _List CLEAR and DETAILED STEPS we can take to reproduce the issue ourselves… Be descriptive!_

Here’s the steps to reproduce the issue:

1. Play Karelian Lakes
2. Wait until a different player has researched Stagecoach at their Trading Post
3. Build a Trading Post on the same Trading Route

### ▶ EXPECTED RESULT

The Stagecoach tech button shouldn’t be on the inventory if it’s already been researched.
