Crash when rearranging research queue:
......................added several mining productivities to queue, then several research speeds, then removed mining productivities to put them after research speed, then tried adding them to the back of the queue, then game crashed.

Does it happen always, once, or sometimes?
.............so far only once

i will attach factorio-current.log

happened a second time, similar juggling with the research queue, but not exactly the same

See 66172

think i figured it out

for some reason, with repeatable reasearch types, such as mining productivity and research speed, the game will allow you to queue up multiple instances of the SAME LEVEL of research, it will also allow cancellation of an earlier level of research without removing subsequent levels of the same type of research, these will both cause a crash.
