in our hamachi server, there is no auto-download so you will need to download required files and addons yourself. File Links:

Teletubbies:

Prop Protection

Advanced Duplicator (has to be THIS ONE, other ones will not be compatible.)

Stacker (Click the download button at the top of the first post)

If you already have the same addons from THE SAME LINK then, of course, don't download.
BUT THEY HAVE TO BE THE SAME ONE MENTIONED IN THE LINK, COPIES OR RE-UPLOADS DON'T WORK CORRECTLY WIITH OTHER PEOPLE IN THE SERVER! An easy way to download these is auto-downloading from the dedicated server that will come out soon.
