First sorry for my bad english. I was writing 3d map with HOKUYO URG 04LX on LOAM-continuous. On April, I didn't surface this problem, but after I'd reinstall ubuntu, I can surface this problem.

[ERROR] [1687669475.808384709]: Ignoring transform for childframeid "camera" from authority "unknown_publisher" because of a nan value in the transform (nan -nan nan) (nan nan nan nan)

ERROR TF re-parenting contention: * reparenting of [/camera] to [/camerainit2] by [/loamcontinuous/transformMaintenancect] * reparenting of [/camera] to [/camerainit] by [/loamcontinuous/laserOdometry_ct]

ERROR TF multiple authority contention: * node [/loamcontinuous/transformMaintenancect] publishing transform [/camera] with parent [/camerainit2] already published by node [/loamcontinuous/laserOdometryct] * node [/loamcontinuous/laserOdometryct] publishing transform [/camera] with parent [/camerainit] already published by node [/loamcontinuous/transformMaintenance_ct]

I think this problem caused by LOAM-continuous, but i've never permute LOAM-continuous code. please help me..
