Dear DeepScanBot,
May I know what the source is that you are using to realign the roads? For example, the junction configuration is wrong, and unnecessary alignment is performed near https://www.openstreetmap.org/#map=22/1.3503836226915404/103.69942782203739. 

You made other wrong changes on the oneway highway by reversing the direction of the highway and deleting the highway segment unnecessarily (way/527683840). Your edit left untagged nods (node/6056618577).

Please go through the policy regarding the https://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct. 

It is also not listed in the https://wiki.openstreetmap.org/wiki/Bot or https://wiki.openstreetmap.org/wiki/Category:Automated_edits_log.
Please follow the OpenStreetMap Editing guideline and respect others edits. As your edits are very large and mix of multi-features edit as same time in a single changeset, if something goes wrong, it would be very hard to revert.

Best,
Jason
