Angry Birds Space HD Free and reading app Instapaper started crashing immediately at launch.
A number of iOS and Mac developers have reported that Apple's App Store updates are having an adverse effect on their apps, according to The Verge.
One complaint comes from Instapaper, which says its 4.2.3 update crashed instantly, even though Apple had given it the green light to be rolled out.
Maker of the app, Marco Arment, contacted fellow developers to find that they had experienced similar problems, while Apple quietly corrected the error behind the scenes without providing him with an explanation.
Angry Birds Space HD Free was also hit by the glitch, and Arment reckons the only way to resolve the issue without Apple's phantom assistance is to delete the corrupt app and install a clean version.
Meanwhile, the GoodReader app team reported the same fault for their past two updates, and claims it's an App Store error which refuses to read certain coding.
