The version of ICO that went up last night was neccessary to verify certain crashes and login problems were fixed prior to the release of Entrenchment beta 2 and Sins 1.13. Unfortunately, there is slight parameter difference between the 1.12 network commands and the 1.13 network commands that ICO is expecting. This causes the crashes. 1.13 will be released very soon, until then play without Alloy if you are experiencing any problems.
In summary: its fixed, we just need to wait for 1.13 to go live.
