I'll give it a go this week to see if I can reproduce it. Ah yes ok then nevermind the Amos thing :) I was not the paying attention properly and someone said that it looked like a bug.
Thank you.
Unfortunately, I can't reproduce the issue.
A few questions:
* which version of the game are you playing (you can get it by typing in a shell: Version "Ring around the World")?
* what are the machine specifications (Amiga model, CPU, OS, etc.)?
* the first time that an object duplicated, what was it and which was the recent sequence of actions until that event?
* could you send me the savegame, please (it's in the "snapshots" directory)?
