The Bugshrrom scene activates when you have at least 3 of lewdness and lust at 40%, which is roughly 2 full bars on the lust meter. After the preconditions are met just keep exploring the forest until finding the item and the option to use it will appear. If your lewdness is higher however, you won't have an option, Leah will use it unconditionally.
Do you have this problem in a single scene, or does it repeat throughout other scenes as well? It seems Parasite Beast scenes are the most affected by this so far, but I could not yet reproduce the bug.
Some tool items, weapons and all original armor are already craftable in the workbench. Some weapons are not yet implemented, but will be slowly added with the next few versions.
Not yet. There is a scene recall feature in the original game, however it'll only be added by version 0.70, so in 2 versions from now

Do you have this problem in all battles or just with a specific enemy?
This is not a collaboration unfortunately

, Atella just gave me permission to use his CGs for the rework and that's all.
There are some quality of life improvements and some other additional features, but as of now, the target is to fully remake the original, before proceeding to extending the story. Any developments after the remake is complete will depend on time, CGs that are available, complexity of features and such, but seeing new scenes of the same animation quality will probably be unlikely, unless Atella agrees to produce some freebies
