I got this bug, I was trying without other mods and same result.

The mod Interplanetary Teleporter (2.0.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event interplanetary-krastorio::on_gui_opened (ID 98)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
[C]: in function 'index'
...ry-krastorio/scripts/interplanetary-teleporter-gui.lua:301: in function 'handler'
core/lualib/event_handler.lua:47: in function <core/lualib/event_handler.lua:45>

Did you use a new save, or did you load an old one?
When exactly did the error occur (e.g., while building, teleporting, loading a save, etc.)?
Also is the dependency “Factorio library” installed?
Because I sadly was not able to reproduce the error on a fresh save with onlt the mod installed.

Yep, I have Flib instaled, bug occur when I clicked on the teleporter after building a second one on another planet.

Really weird — I’ve tried everything I can think of to recreate that kind of bug, but I can’t.
The only thing I can think of is that it might be related to the save file.
If you still get the error even after creating a new save, then it must be something else.

if you find a way to recreate it let me know.

I tested on new save and it works
