UnicodeDecodeError: 'utf-8' codec can't decode byte 0xde in position 0: invalid continuation byte

[hlprimm]

So I'm quite new to python and programming overall. I've managed to get example.py running. I tried it out in test.civcraft.co and it worked great. However, trying it out in the main civcraft server mc.civcraft.co causes this error. Let me know if there's anything else I can provide! BTW, I tried running python 3 on example.py with my login info in the blanks, but it kept throwing this error:

Traceback (most recent call last):
  File "example.py", line 26, in <module>
    from .example_plugin import ExamplePlugin
SystemError: Parent module '' not loaded, cannot perform relative import

So instead I've been running it as python3 -m basic.example ... Not sure if this is causing the problem or not!

Here is the full ouput!

Is there something I should change?

Thanks a bunch, spockbot is AWESOME!!

This is a problem in metadata decoding, probably, armor stands are an old bug that got ignored because they're kinda rare.

Side note: SpockBot was originally built to drive a service called SkyNet on Civcraft, so this is a fun full circle

[gamingrobot]

Fixed fully in #77

[hlprimm]

@gamingrobot thanks a bunch! glad to hear! @nickelpro yeah, i'm doing a similar project to pipe in game chat to my nation's slack chat. super nifty project you guys have going here!!
