Massive lag when getting loot that would include a recipe

Windows 10, Siralim v0.5.6. Whenever the game tries to give me a new recipe (opening a treasure chest, looking at an inscription on a pillar, beating a nemesis pack, etc.) the game lags for about 7-8 seconds, seemlingly frozen (the music even stops) then continues.

The first time it happened I ‘solved’ it by hatching the 400 or so eggs I was carrying around. Now I have no eggs and it’s happening again :frowning:

Update: No lag, and I’m finding new recipes again, both more monsters I’ve already obtained and some that I haven’t. Nothing’s changed besides the patch to v0.5.7.
