This mod is designed for Space Exploration, as the name and description suggest.
When I play 5Dim I'll have a look at it. Unfortunately, I don't have time for it at the moment.

Error while running setup for entity prototype "ion-cannon-targeter" (ammo-turret): next_upgrade target (5d-gun-turret-02) must have the same bounding box.

this issue is caused by 5dim, which modifies my prototype 'ion-cannon-targeter' leading to this error.

I I have forwarded this issue to the 5dim author.
and also implemented a temporary fix, so the ion cannon should load now w/o the error.

Thank you, the endgame without your mod feels incomplete honestly.

On which version of the game is this fixed?
I have the game version 1.1.53, mod version 2.2.1, mod version 5 Dom's Mod - New Battlefield 1.1.6.
I played initially without an Ion Cannon, because I turned on the Rampant biter, but now I realized that there were too many of them and my UPS dropped a lot.
I wanted to turn it on, but it gave me this error.At first, the game asked to disable the mods Additional turrets and Combat Mechanics Overhaul, but after disabling them, the mod still did not turn on.If you turn on the Ion Cannon first,restart the game and then 5DIM's, it will still not work and will ask you to turn off the Ion Cannon.

Sorry, Unfortunately, I don't have time to deal with it at the moment. I also don't use 5dim mods.

this issue is caused because 5dim add new entity level and update the original entity prototype data before you clone data for orbital-ion-cannon

for fixe this issue, you probably need to add this line after cloning data from base entity when you new entity is not upgrade of base (like radar and turret)
entity.next_upgrade = nil

normally there is already this line on the good entities
entity.fast_replaceable_group = nil

you've written that three times now ;-)

the problem is back with the orbital-ion-cannon-mk2 because the addition of the line was put in the data-final-fixes if the line was added in the prototypes just after the clonings the correction would be more solid and will protect from any other mod which has the same goal
