· Manualy joined parts of gcode behave strange
So close!! You almost got it. You actually only have one issue. When it moves the filament from position E1297 to E640 it is moving back about 0.6 meters. That axis (E axis) has it's own speed limit and the move is supposed to be linearly such that it reaches it's X and Y position at the same time as it's new E position - hence it is moving the print head MUCH slower than usual.
Anyway the fix is to tell the printer that we are now already at 640.51694 so it doesn't move backwards.
So you need a G92 E command:
G92 E640.1
Right after printing at E1297 insert the above command. This will tell the printer that the E axis is now at 640.1mm so that when it gets the command E640.51694 it will only move forward slightly. To do it perfectly right - look at the line of code in the original file that you "threw away" and find the last E position before it does the E640.51694. Steal that value and put it after the G92 as shown above.

A little food for thought...
The first line of the vase mode file is an extrusion. It went from a previous point that is no longer in the gcode, to X30.642 Y0.099 E640.51694. In your patched code you are defining the start of that first extrusion as X24.189 Y2.189. Is it close to where it was in the first file? Is it on the correct extrusion path for the vase mode file? You know it wasn't calculated to be on that path.
In this case since it is such a short distance it probably doesn't matter. There are certainly cases where it does matter. If retractions are involved then there would need to be a prime as well.
I would do it this way:
G0 X24.189 Y2.189
;TIME_ELAPSED:1773.432893
;LAYER:20
;TYPE:WALL-OUTER
;MESH:LAMP_SHADE v2.2 wall_0.6_mm.stl
G92 E640.51694
G1 X30.642 Y0.099E640.51694 ;Turn this into just a move that you know is on the vase mode extrusion path
G1 X24.511 Y0.1 Z4.303 E640.72085 ;The G92 line sets the extruder so it is correct at the start point of this line.
G1 X24.423 Y0.917 E640.74819
It's real close to gr5's suggestion. The difference is that without having the exact start of the first extrusion, we ignore it, get to where we need to be, and move on.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
