This is a normal game of "Have you ever?", except it's OGame theme only.
Rules: Someone posts a Have you ever? question, and if you have done it before, you acknowledge it and post a new question. If there is no answer within 12 hours, a new question can be posted by whoever gets there first.
I'll start:
Have you ever: prepared to crash someone who has two colonies in the same system, and after crashing your probe to make a debris field for your recyclers, you realize that you hit the wrong colony and have to send another probe to the correct planet?
