Hey guys!

First time poster here...

I've played a fair way into TTFD. I've been made aware of a research bug and I think I've got it. I have a number of Ion Beam Accelerators but cannot research them...

How do I get around this bug? :S

It's not a "bug", it's a "feature".

No, really - TFTD has a twisted up research tree in order to slow your progress. Catch is it's twisted up to the point where if you get things wrong, you can't complete the game.

Anyhoo, according to the Wiki you need to research stuff in this order:

Deep One Corpse → Aqua Plastics → Plastic Aqua Armour → Ion Beam Accelerators

If memory serves however, I was never able to manufactore the things. So don't sell them until you're sure you don't need them.

So there's no way around the issue for me?! :O

The Ion Beam Accelerators aren't usually the cause of the bugs, but if you have some and they're not showing up for research then something's up. Check your ufopaedia. I'm wondering if you've researched it and forgotten about it. If you have, then that's fine. The sticky point is the live Deep One. You have to have the IBA and plastic aqua armor done before interrogating it. How you go about getting the IBA and aqua armor is up to you.

If that's not the case, then I'd try capturing a Lobsterman Navigator and seeing what that gives you. That's really for the Magnetic Navigation, still... You could also try researching other items like Zrbite or the disrupter pulse launchers if you've picked up a few and see what it results in. Just don't research the live deep-one until you've got the IBA's and plastic aqua armor. At this time, anything's worth a try.

I checked and you were right - I had already researched it!

Upon clicking it I knew the picture but thought it was something else.

As far as I remember I did research IBA and plastic aqua armour before the live deep one. So should I be OK?

Most likely.

For the worst case scenarios, Blade has written a program to deal with tech tree bugs. It's there if you ever need it.

Thanks guys!
