The new update fixes the reactor spawn but the reactor is on top of the radiative towers and I can't place the scaffold
I have also factorissimo 3, and they change tower placement, is that the issue?

Same thing here, only its not on the rediative tower its next to it but still enough to block the scaffold,
and there seem to be some methene icebergs under the reactor blocking the placement aswell.

Due to Christmas holiday travel, my attempted fix earlier today for these particular maps was not successful (due to the issue you described.) This was not caused by Factorissimo 3.

In these instances, I advise you to allow Cerys to regenerate by running '/c game.delete_surface('cerys')'. This will put your character and any overhead space platforms back on Nauvis.

The original issue affected users who started playing Cerys on a version that was on the mod portal for three hours.

Merry Christmas and hope you have fun with the mod.
