How do I remove buildcraft from a Tekkit Classic server OR remove all buildcraft pipes?

[Clean0nion]

I got this issue:

'[buildCraft] Error creating pipe type 0 (class=null)'

I open my server, it's fine. As soon as anyone logs in, lag reaches critical and the server crashes.

The error gives the location of the pipes, but I can't get there due to lag and only having about five seconds to enter a /tp command, and //remove near doesn't work for the same reason.

I've tried MCEdit, but I can't see the pipes, there are purple blocks everywhere, generators look like command blocks, and the lag is too high.

Our world, which we spent many hours on, was unusable. I don't have any plugins to roll back, which I need to get.

So, how can I either disable/remove buildcraft, to prevent this from happening again, or remove all buildcraft pipes from that world, so we can use it again?

I appreciate any help I receive.

In the folder that your server is in, there is a folder called "mods". Before doing the following, back up your world. Then, you delete the .zip called buildcraft(versioning and crap here).zip.

I've tried that. I can't connect to the server, which won't load up anyway.

I have found what I think is a solution: using WorldBan from Tekkit Customiser.
