Sometimes when you spawn a chimera with this weapon the cannon itself moves up when you go foreward and down when you go backwards. As i was testing it i found that when i spawned a new tank this bug would happen if i used the WASD before looking around with the cannon and it wouldnt if i looked around before using WASD. However the weird thing is the bug completely stopped after i spawned a lighting with its variant to see if this applied to it aswel. So not entirely sure whats going on but hope this is helpful anyways.
