1, Place in the map missile specialist with AT-Missile and AP-Missile
2. Make sure your Titan Compact is loaded with AT-Missile
3. Switch your Titan Compact to TOP fire mode (look at the icon in the player interface, it will show that you are currently in top fire mode)
4.Change your missile from AT-Missile to AP-Missile
5. **You will see that the icon still shows that you are in top fire mode, which impossible, because AP-Missile cannot attack from above.**
The fire mode of the Titan Compact should always match the current mode, as it was before update 2.08
