Any template above 28x28x28 will drop a player to single frames when they try to load it, which will cause the template to go holographic which causes massive framerate drops until it is posted or you unload it. Particularly with ones that include many advanced blocks.
This will get worse the more ships and the bigger the structure you paste on.

Couldn't find another task about it, putting in queue. Template preview doesn't perform well, not a bug but it's definitely something that will need to be addressed later on.
