Need some help with explosive jar part

[ROT51]

Rot51, is it always invisible on screen for you? It has always been like this? How about other items you use on stuff in Amnesia? Are they visible?

Second part where i have this exact same problem is when i'am making the Agrippa tonic in the lab. Every item i have to use in there are invisible.

There are no more troubles than these so i'd say the game is working quite well. No lags at all, all levels loads quick. Just these minor issues.
