HOTEND THERMAL RUNAWAY error when printing larger objects

Hello guys,

I was doing some prototyping today, when all of the sudden I start receiving THERMAL RUNAWAY error, and I was amused.

Nothing had changed, and I never had received this error before, so what had happened?

After couple of hours spent investigating, I could find a pattern.

On one specific print, which was done on the FAST slicer option, the extruder would cool down too fast(?) due to movement(?) and it wasn't compensating by heating back up fast enough, so it would end up in a error.

As you can see on this Octoprint graph, the first print would let the temp fall at 195 degrees, then starting to heat back up, this was a smaller print, so no problem.

Then I moved to the next print, which is bigger, and which G Code is provided here: https://pastebin.com/ckPJDnrP

I tried slicing it with slic3r with both options FAST and NORMAL, and it would end up with error THERMAL RUNAWAY, for some reason, it would let the temp fall to 190 degree without compensating, and it would end up in a error..

What should be done? It shouldn't be normal that the preferred slicer slices something that results in something like this..?

Or is there something else that could be wrong?
