Someone spamming level 1 towers. Thanks to choosing paths you can't even upgrade them now -_-
actually players are spamming level 1 towers for 3 reasons
1. Protecting the territory so players cant build in that territory
2. Trollers abuse spamming level 1 towers
3. Beginners spam level 1 sometimes.
Also you can upgrade someone's tower. If your team placed an archer tower, here are steps.
1. Build an archer tower.
2. Choose what path you like. It is either path 1 or path 2.
3. If you upgraded your archer tower in path 1 or 2. Sell your tower
4. Point the minecraft cursor in the archer tower placed by your team
5. Do the shortcut (hold Right click and shift)
6. Congratulations, you have upgrade someone's archer tower.
