This patch should solve the problems some people had with not beeing able to see or connect to any server.
While this patch is not needed to still be able to play Celestial Impact online, it is recommended that everyone download it since it also contains some other bug fixes.
The patch also brings a few gameplay changes:
Grengun has bigger explosion radius and slightly higher damage.
Grengun fire delay is higher
Hitting someone with the railgun now requires slightly more precision than before
Players drop their current weapon when killed
These changes will be in effect for all players on a 1.10b server, even for those still using 1.10
