Compound Psychophract Training Room performance issues

[PaposikG6]

Game becomes extrmely laggy in Compound training room on my save during the fight against four psychophract squads. Unsure if the issue is on my end or if it's related somehow to large amount of psychophracts (normal version of Training Compound battle didn't cause any issues)

Haven't discovered anything out of the ordinary when I tested it. Theoretically, the most likely cause of lag could be due to them trying to pathfind through yet unlowered barriers, but that would apply for any kind of enemy composition.
