With the recent addition of Sansha 'incursions' to EVE Online, activity in certain sectors of the game has increased dramatically. As a result, devs have been tracking issues reported by players and have deployed a patch to address several important concerns.
Based on your feedback, we've cut the system control regain in half. That means Sanshas will regain control much slower than before. This is a first tweak of this value, and we'll be monitoring the Incursions over the weekend to see if this was too much/too little.
The journal, specifically the global report, was not updating properly. We've put in a fix that should make it update accurately.
One of the things we found out initially was that sites were being kept "alive" for a long time after they were completed. The number of players in each system meant that you'd always have traffic going into sites, which means they didn't de-spawn. Hopefully we've dealt with that problem by removing the beacon from overview when a site is completed. This should decrease the traffic going into completed sites. This, combined with optimization of the sites should mean the re-spawning of content is quicker and more graceful.
In addition, developers have started a feedback thread with several targeted questions with regard to future tweaks and improvements to incursion play.
