v2.1.2 - bug-fixing update

👋 Hi!

This is a small update that only fixes some bugs.

Changes:

• If a crash was caused by an addon, the information about addon name is added to crash message
• Fixed a bug that caused addons to not be updated
• Fixed weird auto-pairing behavior
• Fixed a problem that loading syntax could result in a crash
• Fixed #23

😄 Enjoy!
