Delete Invisible Ladders!

Today we have an interesting bug. As you may know invisible ladders are usually placed to fix an OOM area, OP spot, or simple make a map look more open than it actually is.

Yes this item is useful but it has a flaw. Much like placing c4 on grass to destroy it the same can be done to invisible ladder. I messed around with it and found that you can either place the c4;
Below the invisible ladder
One block behind the invisible ladder then right on the invisible ladder block (that's attached to wall)
Or directly on the block that is connected to invisible ladder

Now there is a lot of places where someone can exploit this bug (Don't have pictures for all) but mostly it is the newer maps that are modeled after Black Ops 2.
The only way I can think of fixing this is to;
Replace the invisible ladders with normal terrain block. (That would be visually bad)
Remove c4 completely. (Would upset donors and mc-war would lose a chance to make a profit)
Find or make an invisible solid block so one can not destroy with c4 placements. (Best option visual wise)
Finally have a team completely remake maps with defect. (Process would be time-consuming and player might not like map change)

Any moderator or administrator input on this specific subject would be beneficially to all.

 

I know there are invisible iron doors but those act similar to normal iron doors so I left them out.

It is my goal to get this information to the servers moderators and administrators in the hopes to fix this.

 

Personal reason.

 

Thank you for the clarification.
When you say they wont open iron doors will it say "You don't have permission you do this" when you try too open iron doors?

 

Thank you chickenputty.

 

Lol slapshot suggested earlier today that I should make a thread of "Guess my level".

 

What?

 

You love to kick players...
