Disconnect trying to fly the heli! RPC Error in AddUIFixed
i use /mymini and load this with fuel! Try to get on your seat and get a disconnect.

RPC Error in AddUI
What version of the plugin are you using ? Make sure its the latest 
v0.2.0
How do you have version 0.2.0 when i updated the plugin 3 days ago and this thread is 4 days ago ? Could please double check and if in 0.2.0 because im pretty sure i fixed it.
with the new version after serverwipe the same problem
can you provide more details like when does this happened? what is the error log or even screenshot so i can fix asap
It happens right when I want to sit on the seat.

i will test this on my testserver later
I have tested the plugin on a server that only has fuel gauge. Could tell me the list of plugins you have perhaps i can find something or conflict ?
Just downloaded plugin. Mounted a mini..crashed me to the menu same RPC UI error. Got back in game tried again it worked. Got off heli tried again crashed again.

Alright gonna evaulate each plugin
kicks players when trying to get into transport
Same deal here.  I have the following plugins in common with Cdiehm:
Backpacks, Death Notes, Image Library, Inbound, No Give Notices, Rust Kits, Quick Sort, Sign Artist.

It's sufficent to prevent my players crashing-out by revoking fuelgauge.allow rather than having to remove the Fuel Gauge plugin.

I note that Sign Artist and Fuel Gauge both have a dependency on Image Library, but I'm not in a position at the moment to try removing this plug-in to test if that's where the problem is located.

Hope this helps narrow-down the issue.
This error isn’t a conflict, it just means that the UI being sent was invalid.
same error for me, i removed the plugin now it is good.
when player sit to miniheli or boats, server kicking the player
