When I upgraded this mod today (to v1.4.3), my on-going game said a pile of recipes were removed.
- Any Science
- Any Module
- A few others like grenades.

I reverted back to v1.3.5 and all was good again.

Same here. So I looked at change log and the only record with word "science" was:
Version: 0.2.2
Date: 2020-02-22
Features:
- Added more vanilla recipes, enough that science packs can all be crafted in stacks

So it looks like a bug. Then I looked into code and found it. The fix was easy:

1. open file /utils/deadlock.lua
2. locate local function format(ingredient, result_count)
3. just before this function put the following code:
   local item_types = {
   "item",
   "fluid",
   "ammo",
   "tool",
   "module",
   "capsule",
   "gun",
   "repair-tool",
   "armor",
   "rail-planner",
   "item-with-entity-data",
   }

local function find_item(name)
for _, t in ipairs(item_types) do
local protos = data.raw[t]
local proto = protos and protos[name]
if proto then return proto end
end
end
4. in the function local function format(ingredient, result_count) locate the line:
local item = data.raw.item[ingredient]
and replace it with:
local item = find_item(ingredient)

and enjoy ...

@hnougher can I get a save so I can test this fix

This is my current save.

Should have been fixed in 1.4.4

Thanks. It is working good now.
