Cannot research Plasma Lance after Plasma Rifle

[Starwing]

I'm not using any mods and am playing with all DLC installed. This is my first time playing Shen's Last Gift and I've never experienced this bug before in any of my previous campaigns.

After researching Plasma Rifle, the game notified me that I unlocked upgrades to my Alien Hunter weapons, plasma rifles, and research projects for Plasma Lance, Storm Gun, and Beam Cannon. Unfortunately, Plasma Lance is not in the list of available research, even though Storm Gun and Beam Cannon are.

I want top tier weapons on all my soldiers. Is there anything I can do to fix this, or must I wait for the mythical patch (that probably wont address bugs in the game)?

Weird, maybe the console can help https://www.reddit.com/r/Xcom/comments/44ioyc/xcom_2_console_commands/

Thank you! I hope it'll work.

The only problem is the guide begins with

Go to XCOM2's launch options and add in the line "-allowconsole -log -autodebug" without quotation marks.

Unfortunately, I haven't been able to find the launch options. Can you point me in the right direction, please?

[Zyrrashijn]

Library, right-click xcom2, properties. You'll find it there. -allowconsole is sufficient.

[Starwing]

Thank you again :) I used the console command to add the Plasma Lance technology. I'm really, really glad I don't have to start a new campaign!

And, out of curiosity, did it add the research project and you have to do the research, or did it add the finished research and you can build the PL right away??

[Starwing]

It added the finished research, enabling me to purchase the upgrade right away. To compensate, I've stopped research for a few days.

True to the game rules. Respect

Un-necroing this to add alternate solution because I had the same problem:
Not in the Tech tree, but required: You need to do the Archon Autopsy in addition to Plasma Rifle, and possibly the Gatekeeper. I also had the invisible Plasma Lance problem, but I researched the Gatekeeper autopsy, and then suddenly it was there, greyed out, with 'Autopsy: Archon' as a prerequisite.

[Zyrrashijn]

I think you are confusing the Plasma Lance (sharpshooter weapon) with the Fusion Blade (melee weapon) for which the Archon autopsy is a prerequisite. The Plasma Lance only has the Plasma Rifle as prerequisite.

I know that the wiki does not list the requirement, but I tried it some days ago without any mods and can confirm that you need the Archon autopsy for the Plasma Lance.

You can clearly see that the Archon autopsy is a requirement for Plasma Lance here:

Now all you have to do is change the privacy settings for that Screenshot...

Sorry I thought I did. It's public now.

Archon Autopsy being needed for Plasma Lance was added in WotC.
Which was not yet released when the people in this thread were talking about it.

Now, there's the missing bit that had me confused.
