This is where you will need a migration file.

create /migrations/migration_0.0.1.lua

and put this in it.

for _, force in pairs(game.forces) do
for i = 1, 1000 do
local tech = force.technologies["bullet-damage-"..i] --Local reference to the tech

Which is saying oops, I forgot to add the end for the for loop, after the end for the if check. (updating post above)

I tried changing the break to an end to see if that would work, but it didn't, but ...

local tech = data.raw["technology"]["bullet-damage-"..i] --Local reference to the tech
if tech then --If this tech exists add to it, otherwise break out of the loop
