How to Fix  the Jurassic World Evolution 2 Allosaurus Bug

The Allosaurus bug in the Washington state mission seems to rear its head when:

Another dinosaur gets into the Allosaurus enclosure There’s a break in the fence The environment is glitching the fence

After you’ve built the Arrival point, Control Center, Backup Generator, and Response Facility, you’ll be tasked with repairing the broken fences to create enclosures for the Carnotauruses.

You can use the Ranger Team to fix the enclosures, but don’t miss any repairs. A gap in the fence will cause the objective to glitch. After testing things a few times, it appears an entire section of fence must be missing for there to be a problem; a small gap doesn’t matter for the Allosaurus bug.

The best thing to do here is to demolish all of the fences and build your own. It won’t affect any of the objectives. 

Interestingly, I had a tree clipping through a fence section in the scenario after the Washington state mission, which was glitching out a similar objective for enclosing Carnotauruses safely. I removed knocked down part of the fence, removed the trees with the environment editor, and rebuilt the section. 

If you’ve made sure that there are no gaps in your Allosaurus enclosure, but you still can’t complete the objective, there may be a Compsognathus trapped inside with the Allosaurus. These little critters flitter around the Washington map and can be hard to see because they’re the same tan color as some of the foliage. 

Usually, a Compy is too fast to get caught inside a fence; sometimes they’ll even glitch through the barrier. But if you’ve paused the game to construct an enclosure, it’s possible one is stuck inside causing the bug. If that’s the case, simply destroy part of the fence to let it out.

You could even build a small enclosure around your Allosaurus until the Compy leaves, then expand the pen again. Or, you could fully embrace chaos and let the Allosaurus roam free for a bit. Your choice.

Though it appears the bug keeping some folks from ensuring the Allosaurus is safely enclosed doesn’t seem to be gamebreaking, it’s still worth saving before you transport the dino into its pen. The rest of the Washington state scenario is pretty straightforward. Once you heal the Allosaurus at the Paleo Medical Facility, you’re on to the next campaign location: Pennsylvania.
