Dragon's Dogma Patch Might Corrupt Save Data

According to a post on Capcom Unity, the latest patch for Dragon's Dogma might corrupt your save file. Needless to say, this is a huge problem that hopefully will be fixed sooner rather than later, but for now the folks at Capcom are recommending to backup your saves:
A quick public service announcement for you Dragon's Dogma and Dragon's Dogma: Dark Arisen players. A number of users have encountered an unforeseen issue with a recent downloadable Title Update (patch). The TU, in some cases, has caused players' DD save data to become corrupted (cue Olra purification jokes), meaning the game will no longer save or load their game progress.

To prevent the possibility of permanent loss of your data, please copy your existing save data (whether it be DD or DDDA) to an external storage device or cloud whenever possible--especially if you are picking up the game for the first time in awhile or switching over to Dark Arisen for the first time.

If you experience repeated issues with your save data becoming corrupt, please try playing the game offline while we investigate the issue. We're exploring the issue currently and hope to have a solution as quickly as possible. Many apologies for the inconvenience.

Thanks, IGN.
