Some new bugs in 0.99.30

[chandr]

Sometimes when switching to a character located at a distance from the main group, the inscription "download" appears and the game freezes. I can save the game, but I can not exit.
Also, very often on my base, the part of the territory, in which people could walk freely, becomes inaccessible. Corrected after Ctrl+Shift+F11.
I also confirm the absence of sound, as mentioned in another topic.
I did not have all these errors until 0.99.30
