I fixed bug with VGTU@home magnitude (you could see unbelileveable high magnitude for that project on my pool). But really VGTU not in superblock now and magnitude is zero for that project.
Reason was pool web interface used old status field for project, while really it should use 'present in superblock' flag.
That bug is fixed for now. You can see changes in github repository: https://github.com/sau412/arikado_gridcoin_pool/
User/Project/Host stats also corrected. Reward calculations was not affected by this bug.
