I know some early forecasters in pre-beta are demotivated because of the delay and backlog in reward payments. Here's an update from the team on Telegram on the processing of reward contracts on pre-beta:

Some time ago Wings team hired an extra developer to work on the reward contract. Right now they are finishing 1-2 reward contracts every week. But we are still dependent on the projects to transfer the reward tokens into the  contract after it is finished. A Wings team member confirmed that they expect (not promise!) to finish all reward contracts from pre-beta by the end of the summer!
