Never tested this, only used to see lift spawned and thought it's working but nah.
Players reported to me recently that if you put car on the lift you can't modify it.
Down below attach the image of the problem when went to see what's going on... Used to reload the plugin but still same error... "Vehicle on the lift is not in editable state" 
Questions:
spawn modularcarlift.static and see if you can reproduce the issue with that lift?Just tested
Also forgot to mention... for some reason player's car was dragged from an invisible power to this monument lift. What do I mean? When they exit the car it auto goes with side slide movement even sometimes fully through rocks/trees until reach this lift. Or just crash when hitting something and stop but still glitching and trying to slide to the final destination - the monument lift. Tested next to car lift but no too close (out of lift range) and if player exit the vehicle, car do slide movement to the lift and stays like ready to be modifi and the car was dragged to it every time. Used to place with Ubertool just normal player placed to lift and wire with test gen then every time worked to modify while on the monument lift nope... But car was still dragged to this monument lift, so just deleted the car and modified new one for the player on the hand placed lift and unloaded monument lifts plugin. That's all I know about the issue
Merged post
I can try later to load the plugin and reproduce the issues and will show video if have the same bug and catch it...
That's a very important detail. There was an issue with a previous version of this plugin where it could spawn more than one lift in the same spot after restarts, since the previous lift would not be removed in some cases. When at least two lifts are in the same spot, one would hold a continuous magnet lock on the vehicle, pulling it from across the map when not occupied. This is very likely the cause of the issue where the car cannot be edited, since only one of the lifts is eligible to edit the car. You should be able toFlammable

ent kill the extra lifts. If you delete too many, simply reload the plugin to bring it back.Yes and I tried to remove them all when unloaded the plugin but after deleting one or two lifts last one stays in godmode, not removable...
Sounds like at least one lift is glitched since you can't remove it. Any time you load the plugin, there will be effectively two lifts. Issue probably won't go away until next wipe.
Does the glitched lift work while the plugin is unloaded? If so, you could remove that lift location from the config for now.
Not sure why it would get glitched in the first place. Similar issues can happen with copy paste where an entity can be improperly spawned and be visible but unable to remove.
does this plug work on latest version ?
