I have noticed one thing that puzzles me? With the same progress online & offline.
Offline I can easily jump over the barricades up through a certain Iron Gate.
Online, I can jump on top of the barricades to wood plank, but it will not let me pass through?
Why the difference between offline and online ?
Being the builder of this age, i can tell you that there is not a bit or byte difference in the gamefiles for off line and on line.
Unfortunately the plasma game engine has many physics issues.
its nearly always possible to pass colliders in one way or the other.
As a test i once builded a transparent closed ball and inside it was a small ball.
when i animated the big transparent one, the small ball falls through it immediately.
That makes it hard for a builder.
i placed plenty colliders around that barricade on the balcony to avoid that you can pass it.
and still you succeed in passing it.
I dont know what to do about it , i can only tell you that it is not intended that way,
not by me and not by Cyan in their ages.
in my ages it is never intended that you can pass a barricade!
A barricade is there to do what a barricade should do , it blocks the passway!
However, you can be sure that there is another way to reach that tower without any problem.
You only have to find how.
You can compare it with a one way road.
its not immpossible to enter that road from the wrong side , but you simply don't do that because its forbidden.
I hope you can understand that if you succeed in passing obstacles where its not intended , you also reach places in a way that cant be
avoided by the builder. So if you press buttons or pull switches in an area you could normaly not reach yet, you alter the logic in the wrong moment and ruin the gameplay.
So overall, just play the game, and do not try to reach an area in an unlogic way using weird difficult moves or jumps.
you dont need to have fast gameplay skills, only brains to solve it.
