Known Bugs (TFTD)
Note: Since TFTD shares its game engine with X-Com Enemy Unknown, there are many problems that are common to both games. Please track any shared/common bugs under the XCOM-EU list of Known Bugs (link at the bottom of this page). This page is just for TFTD-Specific bugs.
List of TFTD-Specific Bugs
- Research Tree bugs: see the Research Bug Avoidance Guide for full discussion
- Aliens can't use carried melee weapons (Vibroblades and Thermic Lances), even though they are equipped with them. (This is a game engine bug is present in XCOM-EU as well, but it is not relevant to XCOM-EU, since in XCOM-EU aliens never get equipped with any carried melee weapons.)
- Underwater-only weapons (Torpedo Launcher, HydroJet Cannon, and their SWS equivalents) are able to fire on land during XCOM's reaction-fire phase. This should not be allowed.
- The Bio-Drone's melee attack has no effect, even on unarmoured troops. This is a serious flaw in the Bio-Drone, as it always uses this attack when Aquanauts are adjacent.
- Multi-stage mission bugs: Strange effects occur to Aquanauts who were unconscious and/or under Molecular Control at the end of one stage of a multi-stage mission. These include the Aquanauts becoming invisible, or becoming 'wraiths' in the next mission stage. (Does this also affect XCOM-EU, e.g. the 2-stage Cydonia mission?)
- There is a really annoying "Cannot intercept over land" message that pops up continually (more than once a second) during some pursuits along coastlines. This is probably because the pursuing aircraft is moving rapidly from land areas to sea areas and back again as it flies along a coastline.
- Manufacturing Rate Limit Bug
