Those of you looking to get the Transformers Earthrise Grapple voyager will be glad to know about this issue that has been identified by the facebook group page. It appears the way the peg was made has a tendency to get stuck in the socket due to being a little too large. The fix involved is pretty simple, needing just a small file or other tool to make the peg smaller. See the instructions and images below for the full repair details:
For those that have Grapple, the hole on the feet are just fine, the issue is with the peg. You can see that they are hollow. The head of the peg is where it catches on the hole and makes it hard to pull out, without using a spudger. I've just used a nail file and filed the portion of the head to match the size of the hollow part. I'm not having issues with pulling out the pegs now, even without using a spudger.
The last pic basically shows the cross section of the peg, and all you have to do is file it a bit (where that red line is shown).
Do you have to file the whole peg around or just that one side of the peg shown in the diagram?
