Pretty cool idea for a module, but I think it can be improved
The main issue that makes what could be a fun module instead be a pain in the dookie is the fact that the server list scan only goes up to the first damaged server, making the defusal process waaaaay slower than it should be. The scan should give you the IDs of every server regardless of whether they are damaged or not.
The second issue is the mechanic of the virus spreading. Its already hard enough to try and find the error codes in that huge ass table (r.i.p. paper manual users), but the fact that MORE NODES DAMAGE OVER TIME feels like a really cheap way to double the difficulty of an already very long-winded module.
