Hi Djiyuncin - I am sorry you're experiencing this issue. We have identified and resolved the bug that was affecting games containing drawings yesterday, but, unfortunately we were unable to retroactively resolve it for all users during the affected time. Specifically for the use case where Dynamic Lighting lines were not blocking vision is persisting, the workaround(s) are as follows: 1) In majority of the cases, jiggling the DL lines should resolve the problem. When on DL layer, select all the lines (drag moue or Cntrl A), press right then left arrow keys to shift and put the lines back into the original place. That should work! If it doesn't... 2) Rolling back your game to August 18th will resolve the problem I'm cross-posting an official communication that has been shared below to ensure you have the full information, including one about the rollback process. ---- If you played yesterday and notice any of your Dynamic Lighting not blocking correctly, or drawings that shifted position, rolling your game back to August 18th will resolve the problem. We've temporarily opened up the Rollback feature to everyone, so anyone affected can use it. Steps and FAQs can be found here . Stuck? Contact Customer Service , and we'll help you sort it out! We apologize to anyone who has suffered any inconvenience as a result of this rollout; we are as excited as you are to get Align to Grid back out soon, and we appreciate everyone who tried it so far.
