Hello. Thanks for mapping on this project.
Please solve the issues shown by the issue triangle before uploading your work.
I noticed 5 ends of a road which you stopped wrongly. Instead of just stopping you returned  a bit and mapped it again over the last part.
When you map a trace till the edge of task which continues over the edge, please map it a bit over the edge, The mapper on adjacent task than can pick it up and can continue.
Please use the same tag when an incoming trace is visible on the edge when you extend that trace.
Best regards
