Update 0.6.4 Patch 3 - Minor Update

Hello, Engineers! Like last week, we have two things for you: a developer diary, and more bugfixes! In today's developer diary we are joined by Sergey Leonidov, one of the designers on the Medieval Engineers team. We go into an in-depth discussion about the ideas that went into, and the processes behind, the creation of the new combat system. Additionally, we have a few small changes for you today. The most important one is the fix for the crash to desktop that you have been reporting when placing blocks on the toolbar, or scrolling through the variants. For those technical among you, it was caused by a race condition between the loading thread and the rendering thread. https://www.youtube.com/watch?v=AhXOurqQ7ds Full list of features and improvements: https://forum.keenswh.com/threads/7401972
